The Senate on Tuesday approved Sean P. Duffy’s nomination to lead the Transportation Department in a 77-22 vote, marking an end to an easy confirmation process for the former Wisconsin lawmaker.

The Senate voted unanimously to advance Duffy Monday night, after he appeared before the Senate Commerce, Science and Transportation Committee earlier this month. At the hearing, he was introduced by the two Wisconsin senators — Republican Ron Johnson and Democrat Tammy Baldwin.
