Flake clarified that he wasn't referring specifically to Kavanaugh, but rather, how this process is turning too partisan
"I caught up with Flake briefly as he left the event, and asked if this meant he would not vote to confirm Kavanaugh, even if the FBI cleared him by week’s end. He appeared rattled, and his handlers rushed him into the stairwell. “I didn’t say that …” he stammered. “I wasn’t referring to him."

Flake also told the audience at the Atlantic Festival that, unless there is more evidence that Kavanaugh lied under oath about the Ford incident, he's going to vote yes.
