Brian Cox, the actor most recently known for playing the billionaire patriarch Logan Roy on HBO’s “Succession,” blasted former President Trump in an interview published on Tuesday, questioning how the U.S. voted for “such a f—ing asshole.”

Discussing his new memoir, “Putting the Rabbit in the Hat,” with Deadline, the Scottish actor touched on many of his views that he discusses in the book.

Talking about his character on “Succession,” Cox acknowledged sharing a sense of “disappointment in the human experiment” with Logan Roy.

“I mean when you get to my age, you look back and you say, ‘It’s a f— up,’ ” Cox said.

“Especially if you’ve lived through four years of Trump,” he continued. “You go, how the f— can this country vote for such a f—ing asshole? And yet, this part of this country will, you know, adore him. What is it they adore? What is it they want? And how disappointing that is. So, I feel that disappointment in the human experiment.”

Despite his “disappointment,” Cox expressed some optimism that the situation in the U.S. “may change.”

“We will get better,” he said. “We have moments of greatness in our history, but we have these incredible down moments, and we’ve just been through the riot of Jan. 6 — put the kibosh on everything, as far as I was concerned. And all the love that I had for America, I just thought, ‘What the f—’s going on? What is this? What is this?’ “

The Roy family depicted on “Succession” shares many similarities with the Trump family. Logan Roy, Cox’s character, is an aging conservative billionaire of Scottish origin who has been married numerous times and whose multiple adult children hold positions in his business empire.

Cox has previously commented on the apparent similarities between the Roy and Trump families, telling The Wrap last year that it was the “tragedy of entitlement” that the two families shared.

Describing his show as a “satire of the way things are,” Cox compared the drama depicted on “Succession” to the “entitlement that we’ve seen of the horrific Trumps and Kushner and all of that.”

“We just witnessed the worst element of it ever,” Cox said of Trump’s presidency.
