Obama steps in to support flagging Biden again: Ex-president set to help Joe raise $25million at glitzy New York fundraiser alongside Bill Clinton… while Trump heads to wake of slain NYPD cop Jonathan Diller

Former President Barack Obama is set to lend a hand to President Joe Biden in his 2024 campaign, appearing with Bill Clinton on Thursday at a glitzy fundraiser in New York City at Radio City Music Hall, expected to draw 25 million dollars will fetch.

The Democratic trio will meet some of the wealthiest donors, be interviewed by CBS Late Show host Stephen Colbert and The Office and The Mindy Project star Mindy Kaling will make an appearance.

Meanwhile, Biden’s 2024 rival Donald Trump will attend the aftermath of slain NYPD officer Jonathan Diller at the Massapequa Funeral Home on Long Island.

Diller was shot and killed while on duty in Queens on Monday. Guy Rivera, the suspect arrested in the murder, has been arrested 21 times.

Donors at the Democrat bash will be entertained by musical guests Lizzo, Queen Latifah, Ben Platt, Cynthia Erivo and Lea Michele.

And those willing to donate more than $100,000 to the Biden campaign can have their photo taken with all three presidents.

Obama’s early emergence on the campaign trail seemingly confirms reports that the 62-year-old ex-president has raised alarms about Biden’s reelection prospects.

Time Magazine’s cover story Last week, two in-person meetings Obama had with Biden last year were detailed — one in June and then a follow-up in December, when the ex-president saw the president’s campaign fail to improve.

“He expressed concern that the reelection campaign was behind schedule in building out field operations and was hampered by Biden’s insistence on relying on an insular group of advisers clustered in the West Wing,” Time wrote, citing a Democratic insider.

On Wednesday, an NYPD spokesperson confirmed rumors that Trump planned to attend Thursday's wake at the Massapequa Funeral Home in New York.

A sequel story in The New York Times Tuesday said Obama regularly calls Biden — but he also calls White House chief of staff Jeff Zients.

A senior aide told the newspaper that Obama has “always” worried about a Biden loss to Trump, which is why he is willing to work things out with his former vice president until Election Day in November.

Obama’s reported warnings are similar to what Clinton said behind closed doors ahead of the 2016 presidential election, in which his wife, Democrat Hillary Clinton, shockingly lost to Trump, who had never held elected office.

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

He suggested she go to communities that wouldn’t necessarily vote Democrat, just to show she was doing her best.

“He knew there was some power in showing up,” co-author Allen said in an 2017 interview with ABC News.

Obama has reportedly told Biden that his field operations are being built up too slowly — hampered by the president’s reliance on an “insular group of advisers clustered in the West Wing,” Time said.

During Obama’s 2012 re-election campaign – which he successfully won against Republican Mitt Romney – he had hired more than 900 employees by the summer.

The Biden campaign, headquartered in Biden’s hometown of Wilmington, Delaware, ended 2023 with only about 70 paid employees, although there is a goal to hire 350.

Biden’s team said the campaign also plans to call on Democratic National Committee staff to support efforts at the state level.

And Obama is doing his part – as a powerful way to get donors to give money.

NBC reported earlier this month that the Radio City Music Hall rally is expected to raise $10 million for the Biden-Harris campaign.
