The Republicans won majorities in both the House and the Senate, thus taking control of both chambers.
This is the last congress to have no female members of congress in the House of Representatives, and thus the last time there was an all-male congress (several subsequent congresses, up to the 96th Congress, would have periods with no women in the Senate but several in the House).[3]
