Asked by Real America's Voice host David Brody what might prevent him from running again, Trump answered: 'Well, I don't — I guess a bad call from a doctor or something, right?'
'Things happen. Through God, they happen,' he continued. 'But I feel so good.'
Trump, a hugely polarizing personality who was twice impeached while in office, has made little secret of his ambitions to retake the White House.
Though, he has avoided declaring his candidacy outright, likely on the principle that it is best to be an official candidate for as short a time as possible.
His grip on the Republican party remains strong, as he wishes to show at Saturday's rally, where he will back three candidates seeking the party's nominations.
Trump pledged that the rally would be 'epic' in a fundraising email to supporters this week writing that: 'Georgia is critical to our efforts to take back the House and Senate in 2022, and then the White House in 2024, which is why this rally is so important to me.'
Among his chosen candidates in Georgia is NFL legend Herschel Walker, who recently started a Senate campaign to challenge Senator Raphael Warnock, a Democrat.
Further speaking will be the U.S. Rep Jody Hice, Trump's decision against Georgia Secretary of State Brad Raffensperger.
While Raffensperger, a Republican, declined Trump's entreaties to 'find' enough votes to overturn Trump's narrow loss to Democratic President Joe Biden in Georgia, Hice objected to Georgia's electors in Congress.
Completing the trio is state Senator Burt Jones, an early Trump advocate who pushed measures to overturn Biden´s Georgia win and is running for lieutenant governor.
Ballotpedia, which tracks Trump endorsements, announced that candidates he endorsed have won 37 of 43 competitive primaries since 2017.
