On Saturday, President Donald Trump called his Democratic opponent Joe Biden “dumbest of all candidates.” The president continued on to say, “maybe I’ll sign an executive order that you cannot have him as your president.”

“He is the worst candidate. The dumbest of all candidates. He is the worst candidate in the history of presidential politics,” Trump added.

He once again mentioned how Biden was on drugs by saying, “They gave him a big fat shot in the ass. For two hours, he is better than ever before. Problem is, what happens after that?”

The two candidates’ first debate is scheduled for September 29, with Chris Wallace from Fox News as moderator.

Trump asserted, “We’re going to ask for a drug test. We are. I’d like to have a drug test.”
