Republicans have the House, but there are still tight races that haven't been called

With a call of a House race in Arizona from the Associated Press Wednesday night, Republicans have now won enough seats to control the lower chamber in the next Congress.

That means President-elect Donald Trump will have full control of the levers of power in Washington. But there are still a handful of House races that have not yet been called. Those are listed below.

The size of Republicans' majority was thrown into doubt by the resignation of Florida Republican Matt Gaetz, whom Trump said he will nominate for attorney general.

NPR follows the AP for race calls. Vote are still being tallied in California and elsewhere. Democrats needed a net gain of four seats to win the majority. So far, they have flipped five seats and are leading in one more GOP-held seat. But Republicans also flipped four seats of their own and are leading in one other. If all that holds, Democrats would have seen a net gain of one seat in this election, and Republicans would maintain an even-narrower majority in the next Congress.
