Here's more on the story, from the Washington Times:

Actor Kelsey Grammer reaffirmed his support for President Trump in a U.K. interview Tuesday, saying he doesn’t have many complaints about what the administration had done “in terms of policy.”

The former “Frasier” and “Cheers” star told the BBC Radio 4’s “Today” show that he voted for Mr. Trump in 2016 because he aligned with the Republican president politically.

“I’m a conservative,” Mr. Grammer said. “I have been for a long time. I’m just not a big government guy.”

“In terms of policy, I don’t have a lot of problems with what he’s doing,” he said of the president.

“He’s a bit of a brat, I guess you could say, and that is astounding for people, especially who come from the more liberal side of politics — they’re used to being the brats and so they’ve just never had anybody come back at them the same way,” Mr. Grammer explained. “We’ve witnessed in American politics the same basic language since Ronald Reagan has been attached to every conservative president, but this is the first guy that ever fires back and so it’s really unpleasant.

“And they thought, of course, he shouldn’t be elected anyway,” he added.

The comments made Mr. Grammer a trending topic on Twitter by users apparently forgetful of his history of supporting Republican politicians.

The actor said later Tuesday during a launch event for “Man Of La Mancha” that he was surprised by the reaction.

“It surprises me, but I’m a reasoned, thoughtful guy so I’m not going to say stuff that doesn’t make some sense,” Mr. Grammer said, the Irish Independent reported.

And from Indy100:

Kelsey Grammer and his co-star Danielle de Niese appeared on Radio 4’s Today show to talk about their hit musical 'Man of La Mancha', which is being revived by English National Opera.

Though the discussion was supposed to centre on the show, Grammer veered off course when he talked about Brexit and his support of Trump, before launching into a critique of the "left".

Though he voted for Donald Trump in the general elections, he began by insisting he isn't a "big government guy".

He said: "I’m a conservative. I have been for a long time. I’m not a big government guy."

I do overhear the talk about Brexit and I think, 'Well, why are they voting again for it?'

But that’s a bit like – we do this in America too these days with like well

I think, well couldn’t you vote once? It’s sort of like you keep voting to get the result you want [laughs].

The presenter went on to ask him if he'd changed his mind about Trump given all the controversy around the US president?

In terms of policy I don’t have a lot of problems with what he’s doing, ah, he’s a bit of a, uh brat. I guess you could say.

And that is astounding for people especially for people who come from the more liberal side of politics. They’re used to being the brats. [laughs].

They just never had anybody come back at them in the same way. We’ve witnessed in American politics the same basic language since Ronald Reagan. This is the first guy who fires back so it’s really unpleasant and they thought he shouldn’t be elected anyway.

Grammer has backed Trump many times before, and said he voted for him in 2016.

Back in December, he told Newsweek that Trump has a good chance of winning again in 2020:

Kelsey Grammer and his wife said climate change wasn't a serious issue during a quick interview with TMZ on Saturday. Grammer and wife Kayte Walsh were adamant about the global science concern being a non-issue and stood by President Donald Trump’s decision to hold off on signing a pact to address climate change at the G-20 Summit.

Grammer was slightly more concerned with the world’s warming temperatures than his wife, who spoke candidly in the background about climate change being a myth.

“I do think there’s a warming trend. I’m willing to deal with that,” Grammer said. “You know, when we were kids, we were worried about the next ice age, so something’s happening. Something switched really fast. I think science likes to keep us jumping.”

But Grammer doesn’t necessarily think humans are the only reason for the earth’s warming temperatures.

“We’ll see. Could be sunspot activity. They used to talk about that a lot too,” he said. “But I don’t know. I think man has definitely contributed some to what’s going on in our world. That’s what we do.”

The Trump Administration released the Fourth National Climate Assessment on November 23, which was supported by 13 federal agencies and over 300 climate scientists. The report, in summary, declares climate change is a global issue, which could result in climbing temperatures and lead Earth to someday to be uninhabitable by human life.

Trump denied the findings in the report and claimed he did not believe it. Trump has long opposed the idea of climate change. The rresident explained he had read “some” of the report before making this statement.

Press Secretary Sarah Huckabee Sanders also denounced the study. “We think that this is the most extreme version and it's not based on facts," Sanders said on November 27. "It's based on — it's not data-driven. We'd like to see something that is more data-driven.”

Grammer explained Walsh's remarks, which resulted in a conversation on the administration report. “She thinks it’s a big smoke screen for everything,” Grammer said of his wife’s beliefs.

Walsh responded, “Of course! Everyone is being conned.” When asked if the Trump report could have been fabricated by a paid party she responded: “This whole reality is manipulated.”

Grammer also supported Trump’s decision not to sign the climate agreement at the G-20 Summit. He was the only president who did not sign. “He’s got a couple ideas that might be different about it,” said Grammer.

As for if he sees Trump winning a second term in office, Grammer said, “I think he can win, yeah.”
