Sean Hannity apologized for sharing a fake story about Hillary Clinton on his popular radio show.

The Fox News host had claimed on Tuesday that first lady Michelle Obama deleted tweets praising the Democratic presidential nominee in the face of her ongoing email controversy, implying that the White House was distancing itself from her. Hannity said he found the story on The Gateway Pundit, a conservative site with a penchant for the conspiratorial.

“It says that Michelle Obama had deleted Hillary tweets from her timeline. Did you ever check that out?” Hannity asked his producer on air. When a caller later claimed that President Barack Obama and Sen. Elizabeth Warren (D-Mass.) also removed Clinton-friendly tweets, Hannity ― a vocal Trump supporter ― said “that means they know it’s huge.”

The story could have easily been disproved with a quick Twitter search showing pro-Clinton tweets sent by the Obamas:

Just like Michelle says, when they go low, we go high. @HillaryClinton went high and showed why she'll be a POTUS for all Americans. — President Obama (@POTUS) October 10, 2016

So moved and so inspired by that powerful speech from our next President! #ImWithHer and I am fired up and ready to go. -mo — The First Lady (@FLOTUS) July 29, 2016

Hannity later tweeted that the story was wrong and apologized, but not before it was shared by many conservative social media users ― including several Trump supporters with large followings.

Michelle Obama just deleted ALL tweets for the past 3 years - Why? What is she hiding? Go look for yourself: @MichelleObama — ALWAYS TRUMP! (@Always_Trump) November 1, 2016

Elizabeth Warren just unfollowed Hillary, and Michelle Obama deleted all her tweets about Hillary — Jack Posobiec 🇺🇸 (@JackPosobiec) November 1, 2016

Hannity defended the mistake to CNN, saying that the story “was brought up in an insignificant way, I was dealing with more important issues like HRC crimes and lies and how CNN has been colluding with the Clinton campaign and CHEATING Bernie Sanders.”

But trading in myths is nothing new for Hannity. Most recently, he has reported that the Democratic nominee was drunk at a rally and that her campaign is a “criminal syndicate.” He also invited a man on his show who claimed to have arranged a number of sexual affairs for the Clintons, including a tryst between Hillary and Vince Foster, the White House lawyer who committed suicide in 1993.

It’s worth noting that just weeks ago, Hannity threatened to sue CNN for slander.
