Sen. Markwayne Mullin (R-OK) was confirmed Monday evening by the Senate to replace Kristi Noem as homeland security secretary, even as the agency remains shuttered from an ongoing partial government shutdown.

Mullin was confirmed 54-45 with support from two Democrats, Sens. John Fetterman (D-PA) and Martin Heinrich (D-NM), and nearly all Republicans. Sen. Rand Paul (R-KY), who clashed last week with Mullin at his confirmation hearing and described the nominee as unfit for the job over accusations of promoting political violence, was the lone Republican to oppose.
