DHS Secretary Markwayne Mullin loses temper during hearing

Homeland Security Secretary Markwayne Mullin shouted and clashed with lawmakers at a House Appropriations Homeland Security Subcommittee oversight hearing Thursday, clutching a stress ball as members pressed him on child migration data and rising deaths in ICE custody. Rep. Rosa DeLauro repeatedly interrupted Mullin and called him "belligerent," while Chair Rep. Mark Amodei rebuked Mullin for interrupting and told him, "This is the legislative branch, and it's my hearing." Rep. Lauren Underwood asked Mullin for a policy to prevent detainee deaths; Mullin focused on funding and state prison responsibilities instead of offering a specific federal plan. Hours after the hearing, the DHS Office of Inspector General opened an investigation into the increase in detainee deaths. Mullin previously drew notice for a 2023 hearing confrontation when he challenged Teamsters president Sean O'Brien to a fight, and lawmakers said Thursday's outburst further intensified congressional scrutiny of DHS detention and immigration practices. The IG probe and continued oversight hearings could prompt document requests, subpoenas, and policy reviews of ICE medical care and detention operations.
