The Senate on Thursday voted 54-46 to confirm Tom Perez as secretary of Labor.
It was a party-line vote, with no Republicans supporting President Obama's nominee.
Several GOP senators have charged that Perez had engaged in “ethically questionable” actions while heading the Civil Rights division of the Department of Justice.
Republicans agreed to hold an up-or-down vote on the nomination as part of a deal to avoid the "nuclear option" to end filibusters, but they made clear their strong disapproval of Perez on Thursday.
