TAMPA, Fla. — President Donald Trump is wading into Florida's internal Republican politics, joining his endorsed candidate for governor in a competitive primary.

Trump held a rally in Tampa on Tuesday night in a show of support for U.S. Rep. Ron DeSantis, who faces off against state Agriculture Commissioner Adam Putnam in the Florida GOP primary Aug. 28.

Trump took the stage at the Florida State Fairgrounds shortly after 7 p.m. and spoke for more than an hour.

"He's tough, he's smart and he loves Florida and he loves our country and he's going to be your next governor -- Ron DeSantis," he said. "He's brilliant, a really smart cookie."

Trump also discussed the strong economy, among other things.

"The economy grew at 4.1 percent," he said.

The rally took place on the same day as the beginning of the trial of Paul Manafort, the former campaign chief for Trump's 2016 presidential election campaign.

The trial is the first in special counsel Robert Mueller's investigation into Russian interference in the 2016 election.
