President Joe Biden, facing an onslaught of criticism and concern from allies and voters about his reelection viability, has held private meetings at the White House to reassure supporters that his campaign is strong enough to win in 2024.

Biden held roughly six meetings with top donors and other allies ranging from four to eight people since April, three sources familiar with the discussions told the Washington Post. Though there was no set agenda for the meetings, the talks touched on concerns surrounding the president’s age and his energy, as well as the threat of former President Donald Trump, the Israel-Gaza war, and abortion rights.
