Radio shock jock Howard Stern endorsed presumed Democratic presidential nominee Joe Biden after a Trump supporter defended the president’s comments about disinfectant.

Stern said he was “all in” for Biden on his SiriusXM show Monday, expressing surprise that anyone could defend President Trump’s musings about injections of disinfectant being used as a potential treatment for COVID-19.

“What's it going to take? I don't get it,” Stern said about Trump’s remarks. “I don't think there is anyone left who will vote for him.”

“I am all in on Joe Biden,” the shock jock later said. “You see the wall that's right next to you, I'll vote for the wall over a guy who tells me that I should pour Clorox into my mouth. Listen, I think we are in deep shit. I think we could have been ahead of this curve.”

During the same Monday radio show, Stern also joked that Trump supporters should drink bleach.

“Hold a big rally, say f--- this coronavirus, with all of his followers, and let them all hug each other and kiss each other and have a big rally,” Stern said, adding that they could all take disinfectant and “drop dead.”

Trump made the eyebrow-raising remarks about disinfectant at a news briefing on the coronavirus last week. During the press conference, William Bryan, the head of science at the Department of Homeland Security, told reporters that his team has been working on research regarding how disinfectants and sunlight affects the coronavirus.

“I can tell you that bleach will kill the virus in five minutes. Isopropyl alcohol will kill the virus in 30 seconds, and that’s with no manipulation, no rubbing. Just bring it on and leaving it go. You rub it, and it goes away even faster,” Bryan said before Trump commented on the matter.

“I see the disinfectant that knocks it out in a minute, one minute,” the president said when he returned to the podium. “And is there a way we can do something like that by injection inside or almost a cleaning? As you see, it gets in the lungs, it does a tremendous number on the lungs, so it would be interesting to check that.”

After the controversy, the White House accused some in the media of distorting Trump’s comments. The president also later said he was being sarcastic when he made the remarks about injections.
