U.S. presidents and federal gun legislation: a timeline

Last reviewed October 27, 2026 · 48 sources

Short answer: Most federal gun law comes from a handful of statutes that Congress passed and a president signed: the National Firearms Act (1934, Franklin D. Roosevelt), the Gun Control Act of 1968 (Lyndon B. Johnson), the Firearm Owners’ Protection Act (1986, Ronald Reagan), the Brady Act and the 1994 crime law (Bill Clinton), the Protection of Lawful Commerce in Arms Act (2005, George W. Bush), and the Bipartisan Safer Communities Act (2022, Joe Biden). [48 Stat. 1236 (NFA 1934)] [Pub. L. 90-618] [Pub. L. 99-308] [Pub. L. 103-159] [Pub. L. 109-92] [Pub. L. 117-159] Presidents also shape gun policy through executive orders and agency (ATF) rules, which courts can uphold or strike down.

Hughes Amendment / § 922(o) (1986)

• Added 18 U.S.C. § 922(o), which made it unlawful to transfer or possess a machinegun, except for government use and for machineguns “lawfully possessed before the date this subsection takes effect.” [Pub. L. 99-308, § 102(9)] The act set that provision to take effect on the date of enactment, May 19, 1986, while most of its other changes took effect 180 days later. [Pub. L. 99-308, § 110(a), (c)] This provision is often called the “Hughes Amendment.” The congress.gov record lists it as House Amendment 777 to H.R. 4332, sponsored by Rep. William J. Hughes (D-N.J.), and records that it passed in the Committee of the Whole by voice vote on April 10, 1986. [H.Amdt. 777 (99th Cong.)]
• Barred ATF rules from requiring that dealer records be centralized with any federal or state government, or establishing “any system of registration of firearms, firearms owners, or firearms transactions.” [Pub. L. 99-308, § 106]
• Added 18 U.S.C. § 926A, which protects interstate transportation of firearms by people not prohibited from having them, subject to conditions in the statute. [Pub. L. 99-308, § 107]

Bill Clinton (1993–2001)

Brady Handgun Violence Prevention Act (1993)

Violent Crime Control Act / assault weapons provisions (1994)

Controversy: the 1994 “assault weapons” provisions

• Named firearms. It made it unlawful to manufacture, transfer, or possess a “semiautomatic assault weapon.” The definition began with a list of named models and “copies or duplicates” of them, including certain AK-type rifles (Norinco, Mitchell, and Poly Technologies), the UZI and Galil, the Beretta AR-70, the Colt AR-15, the FN FAL, LAR, and FNC, the Steyr AUG, and the TEC-9. [Pub. L. 103-322, § 110102 (18 U.S.C. §§ 921(a)(30), 922(v))]
• Features test. It also covered any semiautomatic rifle that can accept a detachable magazine and has “at least 2 of” these five features: a folding or telescoping stock; a pistol grip that protrudes conspicuously beneath the action; a bayonet mount; a flash suppressor or a threaded barrel designed to take one; or a grenade launcher. Separate tests applied to pistols and shotguns. [Pub. L. 103-322, § 110102(b)]
• Magazines. It made it unlawful to transfer or possess a “large capacity ammunition feeding device,” defined as a magazine or similar device made after enactment with “a capacity of, or that can be readily restored or converted to accept, more than 10 rounds.” [Pub. L. 103-322, § 110103 (18 U.S.C. §§ 921(a)(31), 922(w))]
• Grandfathering and exemptions. The ban did not apply to firearms “otherwise lawfully possessed” on the date of enactment, or to magazines lawfully possessed on or before that date. Appendix A listed specific models that were expressly exempt; one example is the Ruger Mini-14 without a folding stock. Manually operated firearms were also exempt. [Pub. L. 103-322, §§ 110102–110103, 110106]
• Study and sunset. The Attorney General had to study the law’s effects on violent and drug-trafficking crime and report within 30 months. [Pub. L. 103-322, § 110104] The subtitle was “repealed effective as of the date that is 10 years after” enactment. [Pub. L. 103-322, § 110105]

The definitional dispute. RAND notes that “the term assault weapon is controversial.” It reports that those in the gun industry “argue that the characteristics used to differentiate banned ‘assault’ firearms from nonbanned semiautomatic weapons are cosmetic and do not make them more deadly than similar weapons without those features.” RAND also notes that manufacturers produced models without the listed features, such as folding stocks or bayonet mounts, that were not covered by the ban. [RAND, assault weapon & magazine bans]

What the research found (not the statute). The evidence on these questions is limited, and the reviews below do not settle the debate either way.

• Koper 2004. This is the final evaluation of the federal ban, funded by the National Institute of Justice. It is a grant report, and DOJ notes that it does not necessarily reflect DOJ’s official position.
  • It found that the share of gun crimes involving assault weapons fell by 17% to 72% in the cities studied, mainly through fewer crimes with assault pistols.
  • That decline “was offset” by steady or rising use of other guns equipped with large-capacity magazines.
  • It concluded: “we cannot clearly credit the ban with any of the nation’s recent drop in gun violence.”
  • It added that because millions of pre-ban weapons and magazines were exempt, the law’s effects “would occur only gradually.”
  • On renewal, it said the effects on gun violence “are likely to be small at best and perhaps too small for reliable measurement,” and that assault weapons “were rarely used in gun crimes even before the ban.” [Koper 2004 (NIJ grant report), pp. 1–3]
• RAND (updated January 2026). This review of the research literature rates the evidence:
  • “There is inconclusive evidence for how bans on the sale of assault weapons and high-capacity magazines affect violent crime.”
  • “There is limited evidence that bans on high-capacity magazines decrease mass shootings and fatalities.”
  • “There is limited evidence that bans on the sale of assault weapons and high-capacity magazines increase prices or sales of banned firearms in the short term.” [RAND, assault weapon & magazine bans]

See the 1994 section of our law page for how this history relates to current law.

George W. Bush (2001–2009)

Expiration of the 1994 assault weapons ban (2004)

Operation Wide Receiver (2006–2007)

Protection of Lawful Commerce in Arms Act (2005)

NICS Improvement Amendments Act (2008)

Barack Obama (2009–2017)

Firearms in national parks and wildlife refuges (2009)

Senate votes, April 17, 2013 (no new law). Senate Amendment 715 (Manchin) would have expanded the background-check process. It was “not agreed to” by a 54–46 vote because it needed 60 votes under the Senate’s order. [S.Amdt. 715 (2013)] Senate Amendment 711 (Feinstein), “to regulate assault weapons,” failed 40–60. [S.Amdt. 711 (2013)]

Executive actions — January 2016. The White House announced a package of executive actions. It included ATF guidance that people “in the business of selling firearms” must be licensed and run background checks wherever they sell, a plan to hire more NICS staff, and a final rule on NFA items acquired through trusts and other legal entities. [Obama White House fact sheet, Jan. 2016] That ATF rule was published at 81 FR 2658 on January 15, 2016, and took effect July 13, 2016. It requires background checks for “responsible persons” of a trust or legal entity that makes or receives an NFA firearm. [81 FR 2658]

Controversy: Operation Fast and Furious

The investigation (ATF and the U.S. Attorney’s Office, District of Arizona, 2009–2011).

• The tip. On October 31, 2009, ATF agents in Phoenix got a tip from a gun store about multiple purchases of AK-47-style rifles by four people. Agents came to believe these were straw purchasers for a trafficking ring that supplied Mexican drug-trafficking organizations. [DOJ OIG, Fast and Furious review (2012), p. 1]
• The scale. By the time of the indictment, agents had identified more than 40 subjects tied to the purchase of over 2,000 firearms for about $1.5 million. ATF seized only about 100 of them. The OIG described this as “the result of a strategy jointly pursued by ATF and the U.S. Attorney’s Office that deferred taking overt enforcement action against the individual straw purchasers while seeking to build a case against the leaders of the organization.” [DOJ OIG, Fast and Furious review (2012), p. 1]
• The Brian Terry connection. On January 16, 2010, straw purchaser Jaime Avila bought three AK-47-style rifles. ATF learned of the purchase 3 days later and, “consistent with the investigative strategy in the case, made no effort to locate Avila or seize the rifles.” Two of those rifles “were recovered 11 months later at the scene of the murder” of U.S. Customs and Border Protection Agent Brian Terry, who was killed on December 14, 2010. [DOJ OIG, Fast and Furious review (2012), pp. 1–2]
• The prosecution. On January 19, 2011, 20 straw purchasers and traffickers were indicted. As of August 1, 2012, 14 defendants, including Avila, had pleaded guilty. [DOJ OIG, Fast and Furious review (2012), p. 2]
• The false letter. On February 4, 2011, the Justice Department wrote to Sen. Charles Grassley denying the gunwalking allegations. It withdrew that letter on December 2, 2011, “because it contained inaccuracies.” [DOJ OIG, Fast and Furious review (2012), p. 2]

Fast and Furious is sometimes confused with Project Gunrunner. The OIG describes Project Gunrunner as ATF’s “national initiative launched in April 2006 to reduce cross-border weapons trafficking.” [DOJ OIG, Fast and Furious review (2012), p. 25] In April 2011, the Department itself wrote that Fast and Furious, “which is one law enforcement investigation, should not be confused with Project Gunrunner, which is the broader initiative to deal with weapons trafficking along the Southwest Border generally.” [DOJ OIG, Fast and Furious review (2012), p. 331 n.249]

OIG findings (September 2012). Attorney General Eric Holder asked the OIG to review the matter on February 28, 2011. [DOJ OIG, Fast and Furious review (2012), p. 2]

• The investigations. The OIG concluded that both Wide Receiver and Fast and Furious “were seriously flawed in several respects, most significantly in their failure to adequately consider the risk to public safety in the United States and Mexico.” It found that the strategy of deferring arrests and seizures “even when there was sufficient evidence to do so” was “implemented by ATF and the U.S. Attorney’s Office without adequate regard for the risk it posed to public safety.” [DOJ OIG, Fast and Furious review (2012), p. 419]
• Responsibility. The report described “a series of misguided strategies, tactics, errors in judgment, and management failures.” It said responsibility was shared by people ranging from line agents and prosecutors to senior ATF officials in Washington. It also found failures by Department officials, “including failing to respond accurately to a Congressional inquiry.” [DOJ OIG, Fast and Furious review (2012), p. 471]
• The Attorney General. The OIG found that Holder “did not learn about Operation Fast and Furious until late January or early February 2011” and was not aware of the gunwalking allegations until February 2011. It found no evidence that he was told about either operation before 2011. It concluded that his Deputy Chief of Staff, the Acting Deputy Attorney General, and Criminal Division leadership “failed to alert the Attorney General to significant information about or flaws in those investigations.” [DOJ OIG, Fast and Furious review (2012), p. 453]
• Recommendations. The OIG “made six recommendations” on DOJ oversight of ATF, coordination, and wiretap review. It also recommended that the Department review the conduct of the personnel named in the report to decide whether discipline was appropriate. [DOJ OIG, Fast and Furious review (2012), p. 471]

Congress: the contempt vote (2012). The House Committee on Oversight and Government Reform subpoenaed Justice Department documents, including records about how the Department came to withdraw its February 2011 letter. [H. Rept. 112-546]

• Executive privilege. According to the committee’s report, on June 20, 2012, “minutes before” the contempt markup, it received a letter from Deputy Attorney General James Cole saying the President had asserted executive privilege over certain subpoenaed documents. [H. Rept. 112-546, majority report]
• The majority’s view. The majority called the assertion “transparently not a valid claim of privilege given its last minute nature.” It said Holder was in contempt “for failing to turn over lawfully subpoenaed documents explaining the Department’s role in withdrawing the false letter it sent to Congress.” [H. Rept. 112-546, majority report]
• The minority’s view. The committee adopted the report “on a strictly party-line vote,” and Committee Democrats “were unanimous in their opposition.” Their minority views called contempt “an extreme, unprecedented action based on partisan election-year politics.” They also said the majority “ignored documented evidence of gunwalking operations during the previous administration.” [H. Rept. 112-546, minority views]
• The House vote. On June 28, 2012, the House agreed to H. Res. 711, holding Attorney General Holder in contempt of Congress, by a vote of 255–67, with 1 voting “present.” [H.Res. 711 (112th Cong.)]

Donald J. Trump, first term (2017–2021)

Fix NICS Act (2018)

Bump stocks: memorandum, rule, and Supreme Court reversal

• Presidential memorandum — February 20, 2018 (83 FR 7949). Trump wrote that “after the deadly mass murder in Las Vegas, Nevada, on October 1, 2017,” he had asked his administration to review how federal agencies regulate bump stocks. The memorandum noted that “the Obama Administration repeatedly concluded that particular bump stock type devices were lawful to purchase and possess.” It directed the Department of Justice to complete its review and “propose for notice and comment a rule banning all devices that turn legal weapons into machineguns.” [83 FR 7949]
• ATF final rule — 83 FR 66514, published December 26, 2018 (effective March 26, 2019). The Department of Justice amended ATF regulations to classify bump-stock-type devices as “machineguns” under the NFA and the Gun Control Act. [83 FR 66514]
• Court decision — Garland v. Cargill, June 14, 2024 (6–3). The Supreme Court held that “ATF exceeded its statutory authority by issuing a Rule that classifies a bump stock as a ‘machinegun’.” The Court reasoned that a rifle with a bump stock cannot fire more than one shot “by a single function of the trigger,” and does not fire “automatically.” Justice Thomas wrote for the majority. Justice Sotomayor dissented, joined by Justices Kagan and Jackson. [Cargill (2024)]
• Rule removed — May 2026. ATF later removed the bump-stock language from its regulatory definitions of “machine gun” (see below). [91 FR 24348]

Joe Biden (2021–2025)

Frame-or-receiver (“ghost gun”) rule (2022)

Bipartisan Safer Communities Act (2022)

• Added extra NICS steps for buyers under 21, including outreach to state juvenile-record sources. A transfer may proceed after 3 business days, or up to 10 business days if NICS flags a possibly disqualifying juvenile record for further investigation. [Pub. L. 117-159, § 12001]
• Redefined who is “engaged in the business” of dealing firearms, replacing “principal objective of livelihood and profit” with “to predominantly earn a profit.” [Pub. L. 117-159, § 12002]
• Created federal straw-purchasing and firearms-trafficking offenses (18 U.S.C. §§ 932–933). [Pub. L. 117-159, § 12004]
• Added “dating relationship” to the domestic-violence misdemeanor provisions. [Pub. L. 117-159, § 12005]

Executive Order 14092 — March 14, 2023 (88 FR 16527). This order directed agencies to “pursue every legally available and appropriate action to reduce gun violence.” In it, Biden also called on Congress to act by, among other things, “banning assault weapons and high-capacity magazines” and “requiring background checks for all gun sales.” [E.O. 14092]

“Zero tolerance” dealer-enforcement policy (2021)

• transferring a firearm to a prohibited person;
• failing to run a required background check;
• falsifying records;
• failing to respond to an ATF trace request; or
• refusing an ATF inspection. [White House fact sheet, June 23, 2021]

The policy was repealed in April 2025 (see below). [ATF press release, Apr. 7, 2025]

“Engaged in the business” dealer rule (2024)

Controversy: the pistol “stabilizing brace” rule

• ATF final rule — 88 FR 6478, published January 31, 2023. The Department of Justice amended the regulatory definition of “rifle” to include a weapon equipped with a “stabilizing brace” that provides surface area allowing it to be fired from the shoulder, when other factors also show it is designed and intended to be fired that way. The rule took effect on publication. Braced weapons that it made “rifles” under the NFA had to be registered by May 31, 2023. [88 FR 6478]
• Court challenges. Lawsuits alleged that the rule violated the Administrative Procedure Act. ATF’s own later summary says that within four months of taking effect the rule had been enjoined as to several groups of plaintiffs, that it was universally stayed by a Texas federal court on November 8, 2023, and that “for all intents and purposes, ATF has never actively enforced the 2023 final rule.” [91 FR 24453 (proposed), 91 FR 24455–24456]
• Court decision — Mock v. Garland, June 13, 2024. The U.S. District Court for the Northern District of Texas held that the rule “was arbitrary and capricious and was not a logical outgrowth of the Proposed Rule,” and ordered that it “is hereby VACATED.” [Mock v. Garland, Final Judgment (N.D. Tex. 2024)]
• Appeal dropped. The government appealed, but in July 2025 the appeal was dismissed after the parties filed a joint stipulation. [Mock v. Bondi, appeal dismissed (5th Cir. 2025)]
• Proposed removal — May 2026. ATF proposed removing the rule’s text from its regulations (see below). [91 FR 24453 (proposed)]

Donald J. Trump, second term (2025– )

Executive Order 14206 (2025)

Repeal of the “zero tolerance” policy (2025)

NFA tax change (2025)

Recent agency rules (2026)

• 91 FR 24348 (May 6, 2026): ATF removed the two sentences that brought bump stocks into its regulatory definitions of “machine gun,” in response to Garland v. Cargill. [91 FR 24348]
• 91 FR 24453 (May 6, 2026) — proposed rule: ATF proposed removing the two paragraphs the 2023 rule had added to its regulatory definitions of “rifle.” It stated that courts “have enjoined, stayed, or vacated the final rule, which has rarely been in effect.” Comments closed August 4, 2026. [91 FR 24453 (proposed)]
• 91 FR 24424 (May 6, 2026) — proposed rule: ATF proposed removing the 2024 rule’s added definitions and rebuttable presumptions about who is “engaged in the business” of dealing firearms. It said the changes “have not shown the expected impact” on licensing and enforcement. Comments closed August 4, 2026. [91 FR 24424 (proposed)]
• 91 FR 54054 (August 20, 2026; effective September 21, 2026): The Department of Justice set out criteria for granting relief from federal firearms disabilities. [91 FR 54054]
