Bill Ackman heckled Joe Biden, and it didn't end well for Ackman
And the way Biden responded shows his personality is still fiery as ever.
The former vice president was speaking at a private dinner during last month's SALT conference in Las Vegas. At one point, former presidential candidate Jeb Bush, also in attendance, asked Biden why he didn't run in the 2016 election, according to a Fox Business account published Friday.
Biden reportedly responded by talking about his late son Beau Biden, who died in 2015 from brain cancer, and the room fell silent, according to the account. Biden then stopped himself.
"I'm sorry … I've said enough," he said.
That's when Ackman intervened with an apparent attempt at a joke:
"Why? That's never stopped you before," he said.
Biden didn't take kindly to Ackman's jab. From Fox Business:
A spokesman for Ackman downplayed the interaction, but didn't refute Biden's language.
Biden's near-candidacy was a popular topic at the SALT conference. In one speaking appearance that week, Biden publicly said of Hillary Clinton: "I never thought she was a great candidate. I thought I was a great candidate."
But it took until Friday for news of the Ackman incident to surface.
"Biden was in rare form," a source told Fox Business. "I can't believe it has never leaked out."
The former vice president has not ruled out a 2020 White House bid.
