During a private VIP dinner, former GOP presidential candidate Jeb Bush reportedly asked Biden why he didn’t run, to which Biden said his decision had to do with the death of his son Beau Biden, 46, in 2015 following a battle with brain cancer.

“I’m sorry … I’ve said enough,” an emotional Biden said, according to Fox Business.

Ackman then reportedly interjected: “Why? That’s never stopped you before.”

"Look, I don't know who you are, wiseass, but never disrespect the memory of my dead son,” Biden responded, according to three attendees cited by Fox Business.

Ackman reportedly attempted to apologize when Biden said, “Just shut the hell up.”

A spokesman for Ackman has disputed “the idea that there was an argument or altercation between Joe Biden and Bill Ackman," Fox Business reported, adding that “Bill had a great time at the dinner and enjoyed spending time with the former vice president.”

The former vice president has made several trips helping Democratic candidates across the country as of late, sparking speculation he may run for president in 2020.

Sources told The Hill that Biden regrets not running for president in 2016.

UPDATE: A subsequent report on the meeting published June 26 by New York Magazine disputes Fox's account of the dinner.

Citing four people who were at the event, the report states that Biden called Ackman a "wiseass" after the investor tried to "lighten the mood" with a joke.

"Do you want to take this outside?” Biden reportedly replied. Ackman and others at the dinner thought the vice president was joking, according to New York Magazine.

Biden's comments at the dinner about not running for president because of his son's death were separate from that exchange with Ackman, according to the report.

The sources told the magazine that Biden did not say, “never disrespect my dead son” to Ackman.
