President-elect Donald Trump gave a full-throated endorsement for House Speaker Mike Johnson to retain the gavel in his first visit to Capitol Hill since winning the Nov. 5 election, where Republicans look likely to have control of both chambers of Congress.

While Mike Johnson has no serious challenger, he faces dissent within his ranks, particularly from hard-right conservatives and the Freedom Caucus.

So far Republicans have won 213 races, compared to 203 for Democrats, according to calls made by The Associated Press. It takes 218 seats to win a majority in the House. Of the 19 races that are still too close to call, Republicans were ahead in 10 and Democrats in 9.
