Former President Donald Trump called President Joe Biden a "part-time president," citing claims that Biden's staff admitted he only works from 10 a.m. to 4 p.m., the AP reported.
He also expressed concern about inflation, stating, "I think your real inflation is over 50%," while sharply contrasting Biden's vacation time, noting that Biden has spent "50% of his presidency on leave".
"In November, we will sweep them all out of office," Trump said, vowing to defeat the Democrats " with devastating results".
Trump challenged US President Joe Biden to a rematch in this week's debates and to an 18-hole round of golf during his rally in Doral, Florida.
"Tonight I am officially offering Joe a chance to redeem himself in front of the world," Trump said, challenging Biden for a rematch in the debates.
"Let's have another debate this week so sleeper Joe Biden can prove to everyone in the world that he has what it takes to be president,'' he said, adding that "this time it will be a man against man", no moderators.
Trump continued to imitate Biden's golf swing and challenged him to an 18-hole golf match, promising to donate $1 million to a charity of Biden's choice if he won the game.
At a recent rally in Florida, Trump commented on the cognitive abilities of former House Speaker Nancy Pelosi.
Trump peppered supporters with questions, asking if they had seen Pelosi recently, hinting that she was not feeling well and hinting that her condition might be worse than that of President Joe Biden.
"She is doing worse than Joe,", Trump said.
