President Joe Biden is scheduled to make two appearances next week in Las Vegas, with speeches planned at the 115th NAACP National Convention and at the Unidos US Annual Conference to bolster the Black and Latino votes.

The president’s visits are part of a campaign swing to Texas and Nevada, the White House announced Sunday. The speeches will come as Biden fights calls for him to vacate the Democratic presidential nomination. Questions about the 81-year-old’s fitness for office and cognitive abilities followed his disastrous debate performance against former President Donald Trump on June 27.

On July 15, his campaign trip will land in Austin, Texas, where he will observe the 60th anniversary of the 1964 Civil Rights Act at the LBJ Presidential Library, according to the statement.

Biden will then fly to Las Vegas later that day before his speech on July 16 at the 115th NAACP National Convention at Mandalay Bay, the White House said.

On July 17, the president will address the Unidos US Annual Conference at the MGM Grand.
