US President Joe Biden will Thursday give his first press conference since his debate disaster against Donald Trump, in a pressure-cooker moment that could seal the fate of his reelection bid. The White House has dubbed it a "big boy" press conference, and Biden will be under severe pressure to show he can handle what has become a rare unscripted moment in his presidency. But many Democrats are believed to be waiting to see if Biden pulls off his first solo press conference since November 2023, or whether it will be a repeat of the debate. - 'Devastating' -White House Press Secretary Karine Jean-Pierre has repeatedly promised Thursday's "big boy press conference" — a phrase first used by a journalist that she has since adopted — will feature multiple questions. "It's devastating to say it, but the Joe Biden I was with three weeks ago at the fundraiser was not the Joe 'big F-ing deal' Biden of 2010," wrote Clooney.
