Former President Donald Trump, who four years ago called on Joe Biden to take a drug test prior to the pair’s first debate that September, decided to make the same demand on Friday—one that Biden is sure to wave away once more.

At a campaign rally in Minnesota—where he said he would never return if he lost the state in 2020—the indicted former president recycled his old line of attack against the now-president in advance of the debate next month on CNN.

“I just want to debate this guy, but you know, I’m going to demand a drug test, by the way. I am, I really am,” Trump told supporters at the state GOP Reagan Dinner in St. Paul.

Trump then reiterated what has become a right-wing talking point on Fox News and other platforms regarding Biden’s State of the Union address, which seemed to quell criticisms of the president’s demeanor.
