Three races for the U.S. House in Pennsylvania remained uncalled by The Associated Press on Wednesday, as vote counting continued and Republicans fought to keep their slim majority in the chamber. A House majority would give the GOP a full sweep of power in Congress alongside President-elect Donald Trump in the White House.

Republicans return to Congress for the lame duck session to decide on government funding, leadership elections in both chambers, and whether to cut a deal with Democrats or push the issue into next year.
