Trump boosts GOP House candidate in California

President Trump is reiterating his support for a Republican House candidate in a tough race in Southern California.

The president's campaign issued a statement in support of Diane Harkey, who battling Democrat Mike Levin in the coastal 49th Congressional District. The seat is held by retiring Republican Rep. Darrell Issa.

The 49th district is closely divided politically, and Issa survived by a mere 1,600 votes when he was re-elected in 2016.

Trump's campaign said Harkey would be a "great supporter" of his agenda. The president also endorsed Harkey in a tweet in August.

The statement came on the same day former Vice President Joe Biden campaigned for Democratic House candidates in Orange County.

Democrats are targeting a string of GOP-held House seats in California that Hillary Clinton carried in the 2016 presidential race, including the 49th.
