WASHINGTON, DC - JULY 8: U.S. Sen. Mark Warner (D-VA) departs the Capitol following a vote on July 8, 2024 in Washington, DC. Several Democratic members of Congress have urged President Joe Biden to withdraw from the presidential race after his June 27 debate against presumed Republican nominee Donald Trump. Concerns about Biden's age and perceived slowing down have intensified, with critics fearing these issues could undermine his ability to effectively challenge Trump in the upcoming election.
