The ex-president earned huge cheers as he told the crowd at the Conservative Political Action Conference that he may try and win back the White House.
Mr Trump made the claim as he told the conference audience in Orlando, Florida, that Mr Biden had endured “the most disastrous first month of any president in modern history.”
And he said that Mr Biden’s immigration policy should result in big losses in the 2022 mid-terms and in the 2024 presidential election.
“Actually, as you know they just lost the White House, but it’s one of those — but who knows, who knows, I may even decide to beat them for a third time, OK?” said Mr Trump.
Earlier in his speech, Mr Trump brought back his “China virus” slur when he referred to the coronavirus pandemic.
