The Senate on Tuesday evening confirmed Chris Magnus to head U.S. Customs and Border Protection, the Homeland Security law enforcement agency dealing with a record number of migrant crossings at the southern border.

The 50-47 vote for the Tucson, Ariz., police chief makes him the first Senate-confirmed commissioner of CBP since 2019.

Magnus was nominated for the role by President Joe Biden in April. However, his nomination was held up for months by Finance Chair Ron Wyden, D-Ore., over concerns about the force CBP agents used to quell civil rights demonstrations in Portland last year. The committee advanced Magnus’ nomination last month.
