The Senate on Monday confirmed Markwayne Mullin as the new head of the Department of Homeland Security, placing a close ally of President Donald Trump in charge of the nation’s immigration enforcement apparatus at a politically sensitive moment.
Mullin, 48, was approved in a 54–45 vote, with nearly all Republicans backing his nomination along with two Democrats. However, Rand Paul broke with his party to oppose the nomination following a contentious confirmation hearing.
Mullin secured Democratic support from John Fetterman and Martin Heinrich, helping to ensure his confirmation.
A member of the Cherokee Nation and a first-term senator from Oklahoma since 2023, Mullin now takes charge of DHS at a time when public opinion on immigration enforcement is shifting.
Recent polling indicates that Republicans’ traditional advantage on immigration policy is narrowing, with growing concern among Americans that enforcement actions have gone too far. The backlash intensified after the fatal shootings of two U.S. citizens in Minneapolis earlier this year during federal immigration operations.
As homeland security secretary, Mullin will face the dual challenge of restoring confidence in the agency while advancing the administration’s aggressive immigration agenda, including President Trump’s pledge to carry out mass deportations.
