The owner of the NFL’s Carolina Panthers slammed President Trump on Thursday, saying his attack on players’ national anthem protest is “the biggest pile of bull-dinky ever.”

Hedge fund mogul David Tepper, who bought the Panthers in May for $2.2 billion, said Trump is flat-out wrong for attacking the protesting players as being unpatriotic.

NFL players are the “most patriotic people” in the country — with substantial charitable contributions to their local communities, Tepper said in an interview on CNBC.

Tepper did not mention Trump by name, instead seemingly referring to him as “Howdy-Doody” and as the “red-headed guy in DC.”

During the interview, the hedgie recited the Pledge of Allegiance, calling it “one of the most patriotic you can do.” Tepper emphasized during his pledge the words, “and justice for all.

Trump has been in a long-running battle with the NFL and its players over the move by some players to kneel during the national anthem as a protest against instances of police injustice.

On Sunday, Trump continued his practice of sounding off against protesting players — claiming it’s why NFL ratings have dropped.

“If the players stood proudly for our Flag and Anthem, and it is all shown on broadcast, maybe ratings could come back? Otherwise worse!” Trump said in the tweet.

Tepper gave a special shout-out to the charitable foundation led by Panthers quarterback Cam Newton, which is committed to “enhancing the lives of youth by addressing their education, physical and social needs.”

It wasn’t the first time Tepper sounded off against Trump. In the run-up to the 2016 presidential election, he had harsh words for both Trump and his Democratic rival, Hillary Clinton.

“You have one person with questionable judgment and the other person may be demented, narcissistic and a scumbag. Not saying which one’s which. You can make your own decision on that,” Tepper said in October 2016.

Tepper also voiced criticism of Trump’s tax cuts, saying “some of the tax things were good and some were not so good.”

“We’ll probably have to have some payback at some point,” he added, noting that the cuts were steep.

The hedgie, who manages the $14 billion Appaloosa Management, appeared on air to announce the “Tepper Quad” at Carnegie Mellon University, where he received his master’s in business administration.

Carnegie Mellon’s business school was named after Tepper in 2004 after he made a $55 million gift. Tepper, a native of Pittsburgh, has continued to make gifts to the university since then.
