“I will be strongly demanding a Drug Test of Sleepy Joe Biden prior to, or after, the Debate on Tuesday night. Naturally, I will agree to take one also,” Trump wrote. “His Debate performances have been record setting UNEVEN, to put it mildly. Only drugs could have caused this discrepancy???”

Even Biden had to chuckle at Trump’s latest taunts, although the Democratic nominee opted against saying anything when a reporter asked him later Sunday about the president’s demand.

“He’s almost …,” Biden said before interrupting himself. “No. I have no comment.”

Later, the Biden campaign reconsidered.

“Vice President Biden intends to deliver his debate answers in words. If the president thinks his best case is made in urine he can have at it,” said Kate Bedingfield, Biden’s deputy campaign manager. “We’d expect nothing less from Donald Trump, who pissed away the chance to protect the lives of 200K Americans when he didn’t make a plan to stop COVID-19.”
