The Republican field for president is becoming more crowded.

Sen. Tim Scott of South Carolina jumped into the race Friday, filing as a candidate with the Federal Election Commission. He joins former President Donald Trump, former United Nations Ambassador and South Carolina Gov. Nikki Haley, former Arkansas Gov. Asa Hutchinson and others in seeking the GOP nomination.

And the pool of candidate is expected to grow beyond that.

Here is a look at the latest buzz surrounding the newest hopeful and other potential candidates.

Tim Scott

Scott, 57, is expected to announce his candidacy Monday in his hometown of North Charleston, South Carolina. 

While Scott was only polling at 2% in a Reuters-Ipsos poll earlier this week, he enters the race with plenty of cash to spend. Scott has $22 million that he can transfer from his U.S. Senate campaign account to his presidential campaign, which would be the most any presidential candidate in history has started out with.

After Monday’s event, Scott, the lone Black Republican in the Senate, is expected to head to Iowa and New Hampshire, the first two states holding Republican primaries. He’s planning a $5.5 million ad blitz in those states starting as early as next week and running through the first GOP debate in late August. 

Ron DeSantis

The Florida governor, widely considered to be Trump’s biggest threat for the nomination, will announce his run next week, according to multiple reports.

DeSantis, 44, is expected to file paperwork declaring his candidacy Wednesday or Thursday while also making a virtual announcement, possibly in the form of an online video, reports said. DeSantis reportedly has a meeting scheduled for Thursday with donors in Miami.

A speech formally declaring his run is expected the following week.

According to The New York Times, DeSantis told donors in a call Thursday that he and Trump are the only “credible” Republicans in the race and that only he can beat Biden in a general election because “people aren’t going to change their view” of Trump.

Trump has been attacking DeSantis for months. He’s accused the Florida governor of wanting to “destroy” Social Security and Medicare, criticized his COVID-19 pandemic response and called his public fight with Disney a failure.

This week’s Reuters-Ipsos poll had Trump leading DeSantis 49%-21%.

Mike Pence

The former vice president continues to drop hints that he plans to make a White House run, which would put him up against his former boss, Trump. Their relationship soured when Pence refused Trump’s pleas to reject the certification of President Joe Biden’s victory in 2020.

Like other prospective candidates, Pence, 63, has been making the rounds in early-voting states.  

During an event in New Hampshire on Wednesday, Pence told WBZ-TV in Boston: “I've debated Donald Trump many times, just not with the cameras on. I'd welcome the opportunity to bring my ideas forward if I'm a candidate.”

Pence has said he’ll announce his plans “well before late June.”

Allies of Pence announced this week they are launching a new super PAC, called Committed to America, to support his expected candidacy. The organization is being co-chaired by Scott Reed, who managed Bob Dole’s 1996 presidential campaign.

Chris Christie

The former New Jersey governor continues to say he’s considering running for president again, often in the same breath criticizing Trump, whom he once supported.

In an appearance on ABC’s “This Week,” guest host Jonathan Karl and panelists Larry Hogan, the former Maryland governor, and Donna Brazille, a Democratic strategist, pressed Christie on whether he’s planning to launch a White House bid.

The exchange came after Christie, 60, said there is a need for a Republican who will push back on Trump’s comments. 

“You have to get in the ring and do it and take the risk that goes along with that,” Christie said, adding, “These are tough decisions.”

Christie also ran against Trump in 2016.

Glenn Youngkin

The Virginia governor has been sending mixed signals about whether he might enter the race for president. On Thursday, he fueled further speculation by releasing a campaign-style video ad.

The ad, paid for by Youngkin’s political action committee, included excerpts from his recent speech at the Ronald Reagan Library in Simi Valley, California, as well as back-to-back images of both Reagan and him approaching podiums to deliver speeches.

“We can usher in a new era of American values,” Youngkin, 56, says in the video. “President Ronald Reagan changed lives, and now it’s our turn. A time to choose life, liberty and the pursuit of happiness over oppression and dictatorial rule. The stakes are high, and the consequences couldn’t be greater.”

Youngkin told a reporter in early May that he won’t launch a presidential campaign this year, but he and his aides have the left door open for him to enter the race in 2024.

David Rexrode, a senior political adviser to Youngkin, told NBC News in a statement the governor is “100 percent focused on Virginia” and that the video was simply “highlighting his remarks at the Reagan Library last week.”

Doug Burgum

The North Dakota governor appears poised to enter the race, according to multiple reports.

Burgum, 66, acknowledged in an interview this week with the editorial board of The Forum of Fargo-Moorhead newspaper that he is mulling a presidential run

CBS News reported Thursday that Burgum likely will move forward with a campaign, with a final decision expected within the next couple of weeks. Burgum already has begun hiring political consultants who have advised previous GOP presidential candidates, according to CBS.

And Fox News reported that Burgum has been shooting TV ads in preparation of a campaign launch. 

A former software executive serving his second term as governor, Burgum lacks name recognition compared to most of the other candidates or those who are thinking about running. But he told The Forum he believes “there’s a value to being underestimated all the time. That’s a competitive advantage.”

Chris Sununu

The New Hampshire governor told the website Puck on Thursday that there’s a “61% chance” he’ll run for president. 

Sununu, 48, added that he wants to wait until after the state legislative session has concluded to make a decision and that he believes he can make a decision by mid-June.

The Dispatch reported Friday, citing “close allies” to Sununu, that the governor is accelerating his plans to run. Sununu has been pitching his possible candidacy to Republican donors and has found the response encouraging enough to move forward, the website reported.

Others

Former Trump national security adviser John Bolton, former Rep. Liz Cheney of Wyoming, Rep. Will Hurd of Texas and former Energy Secretary and Texas Gov. Rick Perry are among other Republicans who have expressed interest in running for president.

The announced GOP field also includes entrepreneur Vivek Ramaswamy and conservative radio host Larry Elder.
