US President Joe Biden is taking seriously calls to resign as the Democratic nominee and several Democrats believe it is only a matter of time before he leaves.This was reported by sources familiar with the situation, with whom Reuters consulted.

“He’s doing some soul-searching, I know that for a fact,” said one source, who asked to remain anonymous. “He’s thinking about it very seriously.”

Biden, 81, has faced mounting pressure from prominent members of his party. withdraw from a position on the ballot after his poor performance in a debate against former President Donald Trump, the Republican nominee, raised questions about his age and ability to win in November.

The president has pushed back against those calls, arguing that he has won millions of votes in primaries in recent months and is the choice of Democratic voters.

This was reported by another source, a Democratic Party aide in Congress. The president seemed to have given up. after some lawmakers, including Senate Majority Leader Chuck Schumer, called on him to drop out of the race.

“It seems to be a question of (…) when, not if,” the adviser said.

Biden is recovering from COVID-19 at his home in Rehoboth Beach, Del. He did not attend any public events Thursday after completing a trip to Nevada on Wednesday.

After the debates, Biden’s campaign is focused on three of the seven battleground states, a very narrow path to victory, but he has rejected suggestions that he step aside.

“He’s not wavering at all. The president has already made his decision,” said deputy campaign manager Quentin Fulks in Milwaukee, where the Republican convention is taking place. “Joe Biden has announced that he is running for president of the United States. Our campaign is on.”

Another source, a Biden campaign official, said otherwise. “Yes, it’s over. “It’s a matter of time.”
