Tulsa, United States:
US President Donald Trump said on Saturday that he was in good health and spoke extensively about a graduation ceremony where he appeared to show signs of fatigue.
"I'll let you know if something is wrong," Trump said at a rally in Tulsa, Oklahoma, his first campaign event in over three months.
"There's something wrong with (Joe) Biden, I can tell you," added the 74-year-old president, referring to his 77-year-old democratic opponent in the November 3 presidential election.
He called Biden a "helpless puppet of the radical left".
