(CNN) - Republican presidential candidate Rick Perry will have a private meeting with Sen. Jim DeMint on Tuesday during a campaign swing through South Carolina, CNN has learned.
The two Republicans have previously spoken on the phone but have not met in person.
The Texas governor will be in DeMint's hometown of Greenville to roll out his flat tax plan, a central part of his economic agenda. DeMint has spoken favorably about a flat tax in the past.
A DeMint aide confirmed the meeting and noted that the senator also plans to meet with businessman Herman Cain, the current GOP frontrunner, next week.
DeMint, a tea party hero thanks to his uncompromising views on government spending, is one of the most sought-after endorsers of the Republican primary fight.
He backed former Massachusetts Gov. Mitt Romney during the 2008 campaign but has not picked a candidate in the current race, despite meeting with several of them in person.
Privately, DeMint and his kitchen cabinet have been lukewarm about the GOP presidential field, and the senator made clear in email to supporters last week that no candidate has won him over.
"I have no favorite in the presidential race and have no plans to endorse anyone until I find a candidate who earns the trust of grassroots conservatives," DeMint said in the email.
Perry was supposed to take part in a September presidential forum in Columbia organized by DeMint and his allies, but Perry had to cancel at the last minute to grapple with a wildfire threat in Texas.
