Patriots owner Robert Kraft is longtime friends with President Trump. Texans owner Bob McNair has publicly supported Trump and donated more than $1 million to his inaugural committee. Jets owner Woody Johnson doubles as Trump’s ambassador to the United Kingdom.

As for David Tepper, the hedge-fund billionaire reportedly set to buy the Carolina Panthers for $2.8 billion? He’s called Trump a “demented, narcissistic scumbag” and “the father of lies.”

Tepper steps into a battle between the league and the president, a season after Trump called any player who kneels for the national anthem a “son of a bitch.” Trump constantly launched attacks at the league and jabbed its ratings as more players protested police brutality and racial inequality.

Tepper was outspoken against Trump in the run-up to the 2016 election, telling CNBC that Trump’s lack of charitable giving was the deal-breaker.

“During [Hurricane] Sandy, the big Sandy benefit, the big 9/11 benefit, not one dime,” Tepper told CNBC the day before the election. “Not one dime! You can’t tell me this is a charitable, generous person.”

Trump had boasted about his charitable giving during the campaign.

“Trump masquerades as an angel of light, but he is the father of lies,” Tepper said.

Tepper told CNBC he intended to vote for Democrat Hillary Clinton for president. Though Tepper has been outwardly in favor of Trump’s economic policy — recently telling CNBC that a lack of regulations “releases animal spirits” — he doesn’t seem to have changed his tune on Trump the person.

“If you look up ‘demented, narcissistic scumbag,’ you’ll see my name calling Trump that,” he reportedly told a student at Carnegie Mellon University last month. “Just Google those three words.”
