Biden is at the podium to answer reporter questions in his first solo press conference since November 2023, a critical moment for him as he faces growing Democratic pressure to step aside from his campaign.

White House press secretary Karine Jean-Pierre and National Security Council spokesman John Kirby are in the room as are Secretary of State Antony Blinken, Defense Secretary Lloyd Austin and National security adviser Jake Sullivan.

This is Biden's first solo press conference since the APEC Summit in California eight months ago.

Biden, facing a political crisis as Democrats question the viability of his campaign, is minutes away from holding his first solo press conference of the year -- and since the debate two weeks ago.

It's an opportunity for Biden to change the narrative after his poor performance that night triggered a drumbeat of concerns in his own party that he might be too weakened to win against Donald Trump this November.

But any stumbles in the unscripted setting will only add fuel to the fire, despite Biden's repeated attempts to rebuff his critics and his insistence that he is staying in the race.

German Chancellor Olaf Scholz addressed Biden's viability and future during an interview Thursday on the PBS NewsHour, saying, "it would be a big mistake to underestimate the president."

"I just can tell you from my perspective, as someone that is speaking with Biden, he is very focused and he is very, intensely doing what the president of the United States has to do for leading [NATO]," Scholz said.

Scholz said that had not seen moments in his most recent interactions with Biden that indicated the president is not up for another four years.
