A White House official said Trump will address the crowd on Saturday from a balcony on a "law and order" theme. A source familiar with the situation said the crowd could be in the hundreds, and all were expected to wear masks.
Trump on Monday night will stage his first campaign rally since his coronavirus diagnosis in Sanford in central Florida - a state crucial to his re-election hopes. The event will take place at an airport, and the campaign did not disclose if it would be held in a hangar with its doors open, as it has in the past, or entirely outside.
Questions remain about whether Trump, who announced on October 2 he had the virus and spent three nights in a military hospital, is still contagious. Trump told Fox News he was likely to be tested for the virus on Friday.
The illness has kept the Republican president from holding public rallies and attending fundraisers at a critical juncture of the campaign. He trails Democratic rival Joe Biden in opinion polls with just weeks to go before the November 3 election.
Attendees at the Florida rally will be given a temperature check, masks that they will be encouraged to wear and access to hand sanitiser, the campaign said.
White House spokeswoman Kayleigh McEnany said the president was hard at work and ready to go as soon as he got approval from his doctor, telling Fox News, "He wants to talk to the American people, and he wants to be out there."
SECOND DEBATE CANCELLED
Meanwhile, the planned October 15 debate between Trump and Biden was cancelled on Friday, a day after Trump rejected a decision by the nonpartisan commission organising it to change its format to a virtual event to guard against the spread of the virus.
The debate, originally scheduled as a town hall-style encounter in Miami, was intended to be the second of three presidential debates. The final one is planned for October 22 in Nashville, Tennessee. After Trump refused to take part in the October 15 debate, Biden scheduled a televised town hall-style event for himself that evening.
The Commission on Presidential Debates (CPD) said in an emailed statement: "It is now apparent there will be no debate on October 15, and the CPD will turn its attention to preparations for the final presidential debate scheduled for October 22."
Trump and his administration have faced criticism for their handling of the pandemic, as well as for a lax approach to mask-wearing and social distancing in the White House and - in recent days - confusing messages about how ill the president has been.
With Trump's management of the pandemic dominating the campaign, a new Reuters/Ipsos poll showed Americans steadily losing confidence in how he has managed the health crisis - with his net approval on the issue hitting a new low.
White House physician Sean Conley said in a memo released on Thursday that Trump had completed his course of therapy for Covid-19, remained stable since returning home from the Walter Reed medical facility on Monday and could resume public engagements on Saturday.
"There are medical tests underway that will ensure that when the president is back out he will not be able to transmit the virus," McEnany said, adding Conley would lay out the details later. "He won't be out there if he can transmit the virus."
McEnany is one of a string of Trump aides, including his campaign manager, who have tested positive in the last week as the virus spread within the White House and Trump campaign.
Dr Anthony Fauci, the nation's top infectious disease doctor, told MSNBC on Thursday that guidance from the US Centers for Disease Control and Prevention said a patient is considered infectious for 10 days from the onset of symptoms or until two negative molecular diagnostic tests 24 hours apart.
The White House has declined to say when Trump last tested negative for the disease.
ON-AIR EVALUATION
Trump was scheduled to do an on-camera interview with Fox News on Friday night (local time), his first since being diagnosed. Fittingly, given Trump is a former reality television star, Fox said in a press release that Dr Marc Siegel "will conduct a medical evaluation and interview during the programme."
Biden has continued to campaign during Trump's illness, with events scheduled on Friday in Las Vegas, Nevada.
Biden, a former vice president who has sharply criticized Trump's handling of the pandemic, is leading in national polls but the advantage is narrower in some of the swing states that may determine the election outcome.
On Friday afternoon, Trump told conservative radio host Rush Limbaugh he was working to get coronavirus antibody drugs developed by Regeneron Pharmaceuticals Inc and Eli Lilly and Co approved quickly and out to hospitals after his own experience.
He might not have recovered without those treatments to fight his illness, he said, adding his doctors at one point told him: "You could have been very bad. You were going into a very bad phase."
The Trump and Biden campaigns sparred on Thursday over a televised debate that had been planned for next week. Trump pulled out of the October 15 event after the nonpartisan debate commission said it would be held virtually, with the candidates in separate locations, because of safety concerns after Trump contracted Covid-19.
