Donald Trump danced to the YMCA at the end of his first campaign rally since his Covid-19 illness. 

Trump threatened to kiss audience members with the rally being similar to many others during the president's election battle against Democrat Joe Biden.

When he was finished after around an hour, with his new exit song YMCA blaring over the loudspeakers, the president did what has become his trademark dance, pumping his fists somewhat in time to the beat as the crowd roared.

Mr Trump continued to mock Mr Biden for his efforts to encourage social distancing at his campaign events, deriding as "crazy" the circles Mr Biden's campaign uses to delineate individual space.

With three weeks to go before the election, Mr Trump is pushing to correct a deficit in national and battleground state polling. 

That includes in Florida, which is seen as crucial to his re-election chances. Mr Trump narrowly beat his 2016 rival, Democrat Hillary Clinton, in the state by just over 112,000 votes. Some recent polls have suggested a close race in the state, while others have Mr Biden ahead.

Underscoring the importance of Florida, Mr Trump will be back in the state on Friday for another rally, this time in Ocala.

Mr Trump's Sanford rally was his first stop in a busy week that will include events in Pennsylvania, Iowa, North Carolina, Georgia and Wisconsin.

The robust schedule highlights the urgency he is facing to recover from a series of self-inflicted setbacks that have rattled his base of support and triggered alarm among Republicans who fear the White House is on the verge of being lost.
