O’Reilly’s interview with a clearly ill at ease Donald Trump was bizarre, with O'Reilly demanding to know why Trump felt O’Reilly had occasionally been unfair to him.
He also made some borderline strange comments about Melania Trump, Donald’s wife.
He then interviewed all the other contenders with frequent blips in his speech, sounding remarkably off key.
He told the next guest, media expert Bernie Goldberg, he had no questions for him effectively asking him to make up his own.
Here’s a sample of the reaction to the alleged slurring.
