Markwayne Mullin defended his ability to lead the Department of Homeland Security (DHS) and expressed regret for comments about a US citizen killed by immigration agents during his confirmation hearing on Wednesday. The hearing began on an unusually quarrelsome note when fellow Republican senator Rand Paul accused Mullin of encouraging violence against him.
President Donald Trump nominated Mullin, a first-term Republican senator from Oklahoma, to replace Kristi Noem earlier this month. Noem was ousted amid public backlash against the administration's aggressive mass deportation agenda and the deaths of Renee Nicole Good and Alex Pretti in Minneapolis. Mullin struck a conciliatory tone, signalling he would seek to avoid some of Noem's mistakes, but defended Trump's immigration campaign and pressed Democrats to end their blockade of DHS funding, which has been partially shut down since mid-February.
Paul opened the hearing by demanding an explanation for why Mullin had called him a 'freaking snake' and said he 'completely understood' why a neighbour had attacked him in 2017. Paul played a video of Mullin threatening to fight Teamsters president Sean O'Brien during a 2023 Senate hearing. Mullin responded that O'Brien was now a 'close friend' and they had agreed they could have handled things differently. He asked Paul to let him earn his respect, but Paul remained unsatisfied, accusing Mullin of a lack of contrition.
The committee's top Democrat, Gary Peters, seized on Mullin's recent statement that Pretti, a US Department of Veterans Affairs nurse, was 'a deranged individual'. Mullin said he should not have said that and acknowledged he responded too quickly without facts, but declined to apologise to Pretti's family, saying the death was still under investigation. Peters also questioned Mullin's claims about having seen combat. Despite the clashes, all signs point to a quick confirmation, as Republicans control the Senate and have praised his nomination.
