Confronted about this major error, Beck apologized for publicizing the fake tweet, but otherwise refused to back down. He continued to insist that Trump supported Obama in 2008, even though his single piece of evidence was clearly shown to be a hoax.
Beck’s allegations drew the attention of many, including none other than Donald Trump. After his appearance on The O’Reilly Factor last Friday, Trump went after Beck on Twitter. Instead of accepting correction, Beck doubled down on his claim, mocking Trump and telling him to “admit” he voted for Obama. This was all before the tweet was definitively proved to be fake, making Beck look very foolish.
“After Trump slammed Beck for falling for the fake tweet, Beck doubled down Saturday with a tweet taunting Trump, “Why do you keep saying things like you didn’t vote for @BarackObama ?… just admit it @realDonaldTrump.
Later Saturday night, after apparently figuring out he’d been duped, Beck finally took to his Facebook account to apologize for spreading the misinformation.”
