Far right radio personality Rush Limbaugh floated an absurd lie on his program on Friday, claiming Joe Biden’s live DNC acceptance speech the night before was so well-delivered and emotionally poignant because it was actually pre-taped and edited together for broadcast. That claim is totally baseless and easily refutable.

In fact, as this ABC News report confirms, there were roughly three-dozen reporters present—along with TV camera crews and Secret Service agents—at the Chase Center in downtown Wilmington, Del. to watch Biden give his speech in person.

Limbaugh tried to evade directly backing the ridiculous conspiracy theory by using a rhetorical trick commonly deployed by President Donald Trump, of the “people are saying…” variety.

“I have to tell you, let me just review, there are a lot of people I have come to find out who want to know if [Biden’s] speech was delivered live or was it pre-recorded,” Limbaugh began, notably without ever identifying the “people” making the scurrilous, absurd claims. “Now the assumption I think that everybody had going in was he was live because we didn’t hear anything else. And the time came for the speech to happen, the lights went down or came up whatever and here comes [Biden] and starts the speech. Some people are of the opinion that it had to be tape. And that it had to be taped in segments and the segments had to be edited together because plugs is not capable of 22 minutes even reading a prompter with no screw-ups, this is the prevailing theory.”
