WASHINGTON (Reuters) - U.S. Representative Raul Grijalva became the second congressional Democrat to call for President Joe Biden to withdraw from the presidential race on Wednesday, as the fallout from his shaky performance at Thursday's debate continues.

"If he's the candidate, I'm going to support him, but I think that this is an opportunity to look elsewhere," Grijalva, a progressive who represents a district in southern Arizona along the border with Mexico, told the New York Times.

Neither Grijalva's office nor Biden's campaign immediately returned requests for comment. Biden is set to meet with Democratic governors on Wednesday to try to reassure them of his fitness to run against Republican former President Donald Trump in the Nov. 5 election.

Representative Lloyd Doggett became the first congressional Democrat to call for Biden to step down on Tuesday.
