ATF Director Robert Cekada has accepted Chief Counsel Robert Leider's resignation so Leider can resume teaching as an Assistant Professor of Law at George Mason University's Antonin Scalia Law School. Leider arrived in March 2025 after Attorney General Pam Bondi removed predecessor Pamela Hicks on February 20, 2025. During his tenure the bureau in May 2025 replaced a zero-tolerance dealer policy, in April 2026 proposed dropping a 2023 pistol-brace regulation and large parts of a 2024 engaged-in-the-business regulation, and issued National Firearms Act advice after the One Big Beautiful Bill Act set the making-and-transfer tax at zero from January 1, 2026.
