Urged the Trump administration to undo Joe Biden’s unconstitutional rulemaking, including the pistol brace rule and the ghost-gun rule.
Support undoing the Biden administration’s pistol brace rule and ghost-gun rule.
Occurrences
The pistol brace rule ... Multiple courts have already found the rule to be arbitrary and capricious under the Administrative Procedure Act, and it was ordered vacated by the U.S. District Court for the Northern District of Texas. We appreciate the Government’s recent motions to hold ATF’s 5th and 11th Circuit appeals defending the rule in abeyance and to postpone oral argument, and ATF should work quickly to accede to the vacatur given the ongoing litigation. The so-called “ghost gun” rule ... The regulations are currently before the Supreme Court, but ATF should act immediately to rescind this rule.
Evidence
Cornyn and 29 Senate Republicans sent ATF a letter urging it to "identify and rescind" Biden-era firearms regulations, including the "pistol brace rule" and the so-called "ghost gun" rule, and said these "must be immediately rescinded."
ATF says it is "proposing to formally rescind" the 2023 stabilizing-brace rule, and lists only the brace rule in this repeal action; the page is updated May 8, 2026.
Assessments
Cornyn directly supported undoing both Biden-era firearms rules by joining a February 20, 2025 Senate Republican letter urging ATF to rescind the pistol brace rule and ghost-gun rule. However, the documented policy movement only shows ATF proposing rescission of the 2023 stabilizing-brace rule as of May 8, 2026; the ghost-gun rule was not included in that repeal action. Because one of the two promised targets has advanced toward repeal and Cornyn materially advocated for both while in federal office, this is partial delivery rather than full delivery.
