Committee timeline notes that he didn’t want the name of the guy to get out, likely knowing people would then figure out he was a nut. And even after the guy recanted, media ran with it.
Via Daily Wire:
On Tuesday morning, a false allegation of rape launched against Judge Brett Kavanaugh was phoned into the office of Senator Sheldon Whitehouse (D-RI), which passed it on to the Judiciary Committee. On Wednesday, only hours after the media jumped on the story, the man reportedly responsible for the allegations recanted his accusations, tweeting, “Do everyone who is going crazy about what I had said I have recanted because I have made a mistake and apologize for such mistake.”
Both The Hill and CNN ran with the story. The allegations stated that a rape occurred on a boat in 1985, and that 1985 a “close acquaintance” of a Rhode Island constituent “was sexually assaulted by two heavily inebriated men she referred to at the time as Brett and Mark.” That was an apparent reference to Kavanaugh and his friend Mark Judge. The apparent constituent of Whitehouse’s who made the phone call stated he realized that Kavanaugh was one of the men allegedly involved “when he saw Kavanaugh’s high school yearbook photo on television over the weekend.”
