WASHINGTON (Reuters) - U.S. Republican vice presidential candidate Mike Pence on Wednesday said he endorsed U.S. House Speaker Paul Ryan, who is seeking re-election in a primary contest next week.

Pence made the comments in an interview on Fox News, one day after Republican presidential candidate Donald Trump declined to endorse Ryan in the Wisconsin race.
