Abortion & Reproductive Rights

Brian Mast has publicly supported overturning Roe v. Wade and has said he will fight to protect life at every stage. He has backed legislation to ban dismemberment abortion, supported the Born Alive Abortion Survivors Protection Act, and criticized abortion rights proposals as allowing abortion on demand up to birth.

Climate & Energy

Public Safety & Guns

Brian Mast has supported several gun-safety measures, including a temporary AR-15 sales ban, universal background checks, and a proposal modeled on red-flag protections. He later opposed a revised background-check bill and criticized expanded gun-control authority, indicating a mixed position that combines gun regulation with strong Second Amendment protections.
