The FBI is investigating a plot by a Republican-linked operative trying to frame Special Counsel Mueller with made-up allegations of harassment or sexual misconduct. Law Professor Jennifer Taub, who says she was targeted as part of the alleged effort to smear Mueller, tells Ari Melber she “found it really creepy” and doesn’t know Mueller “at all." Taub says she alerted the Special Counsel’s office and that she “assumed” she was “not the only one being contacted."
