Donald Trump has added a press conference at his Mar-A-Lago Club in Palm Beach, Fla., on Super Tuesday, fueling speculations of another high-profile endorsement.

The billionaire will host separate campaign rallies in Ohio and Kentucky during the day Tuesday, before arriving in Florida. Some speculate that Florida Gov. Rick Scott could announce his support of Trump at the press conference, which is scheduled two weeks before Florida's Republican primary.

Scott has not yet endorsed a candidate, but the two-term governor praised Trump's ability to attract frustrated Republican voters in an op-ed published in January by USA Today.

"There is no doubt that Donald is a man that speaks and tweets his mind freely," he wrote. At the time, Scott said he had no plans to endorse a 2016 presidential hopeful before Florida's March 15 nominating contest.

However, now that Trump has earned the endorsements of two other sitting Republican governors, Chris Christie (N.J.) and Paul LePage (Maine), as well as former Arizona Gov. Jan Brewer, Scott could be under pressure to support the billionaire if he's chosen not to back his home state senator and GOP candidate Marco Rubio.

Just last week, the Florida governor refused to rule out the prospect of becoming Trump's running mate should the New York businessman succeed in his bid for the Republican nomination.

"I'm focused on this job. I've got three more years in this job," Scott told reporters, according to the Tallahassee Democrat. "I've been very clear the things that are important to me, the things that we've done here. I think we need to have a president who has a very specific plan on how we're going to get jobs going in this country, just as we've done in Florida … somebody who's going to be absolutely focused on destroying ISIS."

Scott later declined to comment on a potential VP position, responding instead with a description of Trump's campaign as "fun to watch."

Trump's press conference will take place at 9 p.m. ET on Tuesday, just hours before polls close in several of the Super Tuesday primary states.
