An administration official said Trump would rally supporters at an airport hangar there, the same venue where he held a rally in September.
Trump is slated to arrive at the rally by landing at the airport on Air Force One and disembarking in front of the crowd, just as he did during the campaign, the official said.
White House press secretary Sean Spicer said on Wednesday the event was a campaign rally and directed questions about it to “the campaign.” He said Trump’s campaign was paying for it but didn’t offer further details.
Trump indicated in a form sent to the Federal Election Commission on Inauguration Day that he intended to run for President again, but noted it did not constitute the formal announcement of his 2020 candidacy.
Last week, the Office of Special Counsel issued guidance for federal bureaucrats with regard to the nascent re-election effort.
