Last week, former President Trump announced that he would run for the White House a third time.

Some of his strongest supporters in Congress celebrated the announcements, but other key GOP figures are no longer supporting the campaign.

The Republicans are speaking out against Trump in his reelection campaign.

Direct critics and ‘Never-again Trumpers’

Former Speaker Paul Ryan (R-Wis.)

According to Ryan, the GOP will probably lose the White House in 2020 due to the losses of the House and Senate.

Ryan told Jonathan Karl on ABC's "This Week" that he thinks we will win the White House.

The former Speaker referred to himself as a "Never-Again- Trumper".

Virginia Lt. Gov. Winsome Sears

She wouldn't support the former president if he ran for reelection a third time.

I wouldn't support him. The Virginia lieutenant governor said that voters have sent a "very clear message" for Trump to back off.

When a leader becomes a liability, they understand. Sears said that it was time to step off the stage.

Sen. Bill Cassidy (R-La.) 

The seven Republicans who voted to convict Trump were led by Cassidy. Last year, he said he wouldn't back Trump in a bid.

According to Cassidy, the first president in the Republican side to lose the House, the Senate and the presidency in four years was Donald Trump.

Mike Allen said to Cassidy that he wouldn't vote for him.

The senator said he wasn't.

According to Cassidy, the next GOP presidential candidate will be looking to the future, not the past.

Former Secretary of Defense Mark Esper 

He said no when asked if he would vote for Trump in the next election.

I will let you know why. In my opinion, any elected leader needs to be able to put country over self, they need to have a certain amount of integrity, and they need to be able to reach across the aisle and unite the country. "Donald Trump doesn't meet those marks for me."

On "CNN This Morning" last week, Esper said that Trump is "unfit for office" and that the GOP should move on to other candidates.

Former White House communications director Alyssa Farah Griffin

Donald Trump is not fit to hold the office of president. On the day of Trump's announcement, he asked Republicans to take him on.

After leaving the administration, the communications director became critical of the president.

If Trump and Pence ran against each other, they could put up a formidable fight.

South Dakota Gov. Kristi Noem (R) 

Noem said last week that Trump doesn't offer the best chance for the GOP in the next election.

The governor of South Dakota just won her second term and has been mentioned as one of the governors who could run against Trump in the future.

We don't talk to every single American if we narrow our focus. Our job isn't just to talk to people who like or dislike Trump. Noem told The New York Times that they had a job to do.

Gov. Asa Hutchinson (R-Ark.)

There are better choices for the GOP to pursue in the next presidential election, according to Hutchinson.

Trump is correct in his assessment of Biden's failures, but his self-indulging message has not changed. In 2022, it didn't work, and in 2024 it won't work. There are better options.

Last week, the Arkansas governor told CNN's Kaitlan Collins that he is seriously considering his own bid for the presidency in 2024.

Rep. Mo Brooks (R-Ala.)

It would be a bad mistake for the Republicans to have Donald Trump as their nominee in the future, according to an interview with Alabama outletAL.com.

The Alabama congressman who lost to Trump in the state's Senate GOP primary called him "dishonest, disloyal, incompetent, crude."

The lawmaker moved away from Trump's claims that the 2020 presidential election was stolen from him.

Gov. Larry Hogan (R-Md.)

On the day of the former president's announcement, Hogan called on the GOP to "turn the page"

Republicans have done nothing but lose since the beginning of the year. It isn't just foolish to lose. The Democrats will get a gift from it. It's time to turn the page.

Hogan blamed Trump for the GOP's poor showing. The two-term Maryland governor is rumored to be a potential opponent for the former president.

Indirect critics

Former Secretary of State Mike Pompeo 

"We need more seriousness, less noise, and leaders who are looking forward, not staring in the rearview mirror claiming victimhood," said the Secretary of State.

The comment was made after Trump referred to himself as a victim during his speech.

The 2016 and 2020 campaign line that the GOP would get "tired of winning" appeared to be hit by the Secretary of State.

We were told to stop winning. I don't want to lose. He said that most Republicans are also.

There is a possibility that Pompeo could be a candidate for the 2024 presidential election.

Former Vice President Mike Pence

The former vice president has been making digs at his former boss during his media tour to promote his new book.

Pence was asked if Trump should be president again.

"I think that's up to the American people," he replied. Better choices will be made in the future.

When people leave politics, they get along well, according to the vice president. I think there will be better choices in the days to come.

It would be disloyal for Pence or any other former Trump Cabinet member to seek the GOP nomination, Trump said last month.
