NBC News’ Tom Brokaw claimed that President Donald Trump, and “some people on the right,” want “to destroy the prevailing culture in this country,” during an interview Wednesday on MSNBC’s “Morning Joe.”

The veteran NBC News journalist addressed the president’s ongoing feud with the National Football League, which began Friday night at a raucous rally in Alabama. Trump took issue with NFL players who chose to protest racial injustice in the country by kneeling instead of standing for the national anthem, saying their coaches should fire them for disrespecting the anthem and the flag.

Brokaw bemoaned the damage he believes Trump and the conservative-populists have wreaked upon the Republican Party during and after the 2016 presidential election.

“I think there are some people on the Right who want to destroy the prevailing culture in this country. I mean, that’s the way that [Trump] ran, quite honestly,” he said. “But at the same time, for all of the promises that he made during the campaign … not one of them is coming true.”

Brokaw did not appear to be disturbed by the notion that Trump’s signature campaign promises weren’t coming true.

Most recently, the GOP’s promise to repeal and replace Obamacare suffered another crushing defeat Tuesday when Republican leadership pulled the Graham-Cassidy bill that would have reformed Obamacare, due to a lack of 50 “yes” votes.

But Brokaw noted Trump is still popular with his voting base, despite his party’s lack of legislative progress.

“And I, you know — when I go out and talk to people in the West who are Trump voters, they said, ‘We’re still with him. We think it’s your fault, talking about us,'” he said. “But then they’ll say, ‘I wish he would just shut up for a while.’ You know, that he … has to talk about who he is and how great he is. And he gets something back from that, I guess, but it’s not good for the country.”

“The fact is, that I don’t know how this ends up because … on the Republicans’ side of the Hill, they’re holding their heads at this point,” Brokaw continued, noting that Sen. Bob Corker (R-Tenn.) announced Wednesday he would not seek re-election in 2018.

“And we got Corker is not going to run again — I’m sure that this president had something to do with that, and he didn’t want to be in the office when he had that as the leader of his party and the chief executive of the United States,” he claimed. “This is a crisis point for this country.”
