WASHINGTON – President Donald Trump will hold a campaign rally in Tampa on July 31, providing another boost for surging gubernatorial candidate Ron DeSantis.

The 7 p.m. rally will be held at Florida State Fairgrounds. People who want to attend can go here. Doors open at 4 p.m.

It fulfills a promise Trump made when he called into a Hillsborough County GOP fundraising dinner in May and told the audience: "I'll be there fairly soon. We'll hold a special event there in the near future … We'll be in Tampa very soon."

The Trump campaign said Monday evening that, the president "is expected to address the latest record-breaking jobs and economic data from the booming Trump economy, his nomination of Brett Kavanaugh to the Supreme Court, and the importance for Floridians to get out and vote this fall for key races to support his agenda; including to support Rick Scott who is running to defeat Ben Nelson in the U.S. Senate, Matt Gaetz for re-election to the U.S. House, and Ron DeSantis for Governor," Trump's campaign said, mistaking former Nebraska Sen. Ben Nelson for Florida Sen. Bill Nelson.

Trump is also expected to hold a White House event on workforce training, an initiative he's shared with daughter Ivanka Trump. Last week, the president signed an executive order on job training.

DeSantis, who has Trump's endorsement over the objection of some Republicans who think Adam Putnam would be a better general election candidate, has gained momentum in recent weeks, especially after Trump more pointedly signaled his support in late June.

Congressman Ron DeSantis, a top student at Yale and Harvard Law School, is running for Governor of the Great State of Florida. Ron is strong on Borders, tough on Crime & big on Cutting Taxes - Loves our Military & our Vets. He will be a Great Governor & has my full Endorsement! — Donald J.

One question is whether Gov. Rick Scott will attend, even though the campaign announcement names him. Scott's campaign did not say Monday night whether he'd attend.

Once an avid supporter of Trump, Scott has kept a low-profile as he runs what is effectively a general election campaign against Democrat Bill Nelson.
