Chaos as protesters paying up to $500K a ticket heckle Biden, Obama and Clinton at Radio City: Demonstrator tells presidents 'you are out of your f***ing minds' on Russia and Palestinian supporters says they have blood on their hands

President Joe Biden's appearance at a $25 million Radio City Music Hall fundraiser with former Presidents Barack Obama and Bill Clinton got off to a rocky start as the trio of president being interviewed by Stephen Colbert got interrupted by protesters. 

A handful of pro-Palestinian protesters shouted down the trio of presidents, with one woman telling Biden 'you have blood on your hands,' as another loud guest warned of a nuclear war with Russia: 'you're out of your f***ing minds.' 

The event was supposed to be a star-studded evening with major donors, with some tickets costing as much as $500,000. 

Lizzo was there and performed her hit 'About Damn Time' ahead of the presidents' arrival onstage, while The Mindy Project's Mindy Kaling played the role of emcee. 

She joked that it was nice to be in a room with 'so many rich people' and said it felt good to support a president who 'openly' promises to 'raise your taxes.' 

Vogue editor-in-chief and Conde Nast executive Anna Wintour was spotted in the audience.  

Kaling, 44, also said - looking upon Biden, 81, Clinton, 77, and Obama, the youngest at 62 - that while she was getting older, she looked like a 'cast member of Euphoria' compared to them. 

HBO's Europhia is a high school drama, though most of the cast is in their 20s.  

Other entertainers included Queen Latifah, Ben Platt, Cynthia Erivo, and Lea Michele. 

Meanwhile, outside the venue, many more pro-Palestinian protesters had swarmed Radio City Music Hall.

Biden was called a 'war criminal' by those gathered, with one demonstrator holding up a sign that read, 'Joe Biden Retire B****,' a message aimed at the 81-year-old leader.

One video, shared by conservative commentator Charlie Kirk, shows a man getting shoved by members of the crowd and asking for police to assist. 

'Democrats you can't hide, we charge you with genocide!' protesters shouted out, with drum beats helping them keep the time.  

The trio of presidents have been at the venue for most of the afternoon - taping a podcast with comedians Jason Bateman, Sean Hayes and Will Arnett for an episode of their SmartLess podcast. 

Videos shared to social media by attendees show loud music playing as donors took their seats, with audience members seemingly unaware of the chaos happening outside. 

Earlier Thursday, Biden arrived in New York with Obama in tow to New York's John F. Kennedy International Airport. 
On the flight Obama could be heard briefly saying hello to the White House press corps, as press secretary Karine Jean-Pierre told reporters the conversation was off the record. 

Obama's involvement with the Biden campaign comes after several reports said the 62-year-old ex-president has been sounding the alarm about Biden's reelection prospects.

Meanwhile on Thursday, Biden's 2024 rival former President Donald Trump will attend the wake of slain NYPD officer Jonathan Diller at the Massapequa Funeral Home on Long Island.

Diller was shot and killed in the line of duty in Queens on Monday. 

Guy Rivera, the suspect arrested in the slaying, has been arrested 21 times. 

Time Magazine's cover story last week chronicled two in-person meetings Obama had with Biden last year - one in June and then a follow-up in December, when the ex-president didn't see the president's campaign operation improve. 

'He expressed concern the re-election campaign was behind schedule in building out its field operations, and bottlenecked by Biden's insistence on relying upon an insular group of advisers clustered in the West Wing,' Time wrote, citing a Democratic insider. 

A follow-up story in The New York Times Tuesday said that Obama is regularly dialing Biden - but he's also phoning White House Chief of Staff Jeff Zients too. 

A senior aide told the paper that Obama has 'always' been worried about a Biden loss to Trump, and so he's prepared to 'eke it out' alongside his former VP through Election Day in November. 

Obama's reported warnings are similar to what Clinton was saying behind closed doors ahead of the 2016 presidential election, which saw his wife, Democrat Hillary Clinton, shockingly lose to Trump, who had never held elected office. 

In the book Shattered: Inside Hillary Clinton's Doomed Campaign authors Amie Parnes and Jonathan Allen detailed how Bill Clinton feared that his wife and her campaign aides were taking some support for granted. 

He suggested she go into communities that wouldn't necessarily naturally vote for the Democrat just to show she was making an effort. 

'He knew there was some power just in showing up,' co-author Allen said in a 2017 interview with ABC News. 

Obama has reportedly advised Biden that his field operations are being built out too slowly - bottlenecked by the president's reliance on a 'insular group of advisers clustered in the West Wing,' Time said. 

During Obama's 2012 reelection campaign - which he successfully won against Republican Mitt Romney - he had hired 900-plus staffers by summer. 

The Biden campaign, which is headquarted in Biden's adopted hometown of Wilmington, Delaware, ended 2023 with just around 70 paid employees, though there's a goal to hire 350. 

Biden's team said that the campaign is also planning to rely on staff at the Democratic National Committee to aid the state-level effort.
