President Joe Biden and his Democratic predecessor, Barack Obama, headlined a star-studded fundraiser with former President Bill Clinton on Thursday, offering a robust defence of the White House’s handling of the Gaza crisis as protesters interrupted the event, Reuters reports.

Biden, who travelled with Obama on Air Force One to New York, took part in a discussion with Clinton moderated by “The Late Show” host Stephen Colbert at the iconic Radio City Music Hall in front of thousands of guests. Organisers say the event raised more than $25 million for Biden’s US reelection campaign.

But the fundraiser was punctuated by several protests inside the massive auditorium, with attendees rising at several different moments to shout over the discussion, referencing Biden’s backing of Israel in the Gaza offensive that has killed more than 30,000 people.

“Shame on you, Joe Biden!” one yelled.

Obama and Clinton offered a presidential perspective of the Gaza crisis that stressed the political realities of being in the White House. A president needs to be able to support Israel at the same time as fighting for Palestinians to have more access to food, medical supplies and a future state, they said.
