Donald Trump prepared on Friday to return to the campaign trail with two potential rallies at the weekend after his COVID-19 diagnosis sidelined him for a week in the White House race against Democratic nominee Joe Biden.But questions remained about whether he was still contagious and whether his campaign, whose leadership has also been hit hard by the coronavirus, could put on the events at short notice.Trump, who announced on Oct 2 he had the virus and spent three nights in a military hospital, said late on Thursday he was feeling "really good" and aimed to campaign in Florida on Saturday and in Pennsylvania on Sunday.White House spokeswoman Kayleigh McEnany said on Friday the president was hard at work and ready to go as soon as he got.
