Conservative radio host Glenn Beck apologized for claiming that Republican presidential candidate Donald Trump had voted for President Barack Obama in past elections, saying he’d been duped by a fake tweet.

Beck was a guest on Fox News’ “The O’Reilly Factor” last week, making a case for why he thinks “progressive” Trump would be as big of a “monster” as Barack Obama – a case he’s been making for many months.

Trump watched and responded to the show with a slew of unpleasant opinions about “dopey” Beck to a New Hampshire crowd.

When Trump denied ever having voted for the president Beck tweeted:

Why do you keep saying things like you didn’t vote for @BarackObama ?… just admit it @realDonaldTrump pic.twitter.com/ZgL9OAOZck — Glenn Beck (@glennbeck) January 16, 2016

But on Saturday Beck realized he’d been duped by a fake tweet, and was big enough to apologize via Facebook:

Beck’s full apology reads:

****10pm Saturday Update: my apologies for the misinformation. I will always lead with my mistakes. It does appear this to be fake. My fault for not checking it far enough myself. I take complete responsibility for this error. Apparently it comes from this site: http://faketrumptweet.com/ I owe Donald Trump an apology for the error of this tweet. More importantly I owe you an apology for making the water muddy where the water is crystal clear on his record. Update: this is a deleted tweet from the trump Twitter feed. My researchers are split tonight on whether or not this was a hack or fake. I want to make sure that you know from me first that the staff is split down the middle. Not enough to say real or fake at this point. There is no denial from the campaign on this tweet. But I do not want to run anything that is not accurate. If it is deemed a fake you will hear it from me. If it is real, the same. Until we can come to a consensus and feel comfortable I want to let you know that it is in question. There is enough on Donald Trump to not have to make things up. (See the earlier post of him defending abortion and the New York voting difference) I work hard to make sure we get it right as you know. After 3 years on Fox taking on the likes of the White House and George Soros you know we do our homework and if we get it wrong we lead with our mistakes. Stand by.

Editor’s Note: This post originally stated the vote was in 2012 and 2016. This was a writing error and has been corrected to say “past elections.”
