RR involved. Remember the article about Jeff Flake trying to reach Sessions but he got RR instead?
Talking to his colleagues, Flake voiced discomfort with the accusation against Kavanaugh and said he was leaning toward asking for an FBI investigation, according to two people in the room who were not authorized to discuss the private conversation and spoke on condition of anonymity.
Other Republicans entered, including Sen. John Cornyn of Texas, to make their case to Flake. Coons said afterward that Flake's fellow Republicans tried "vigorously" to get him to drop his concerns. According to one person in the room, Flake tried to reach FBI Director Christopher Wray on the telephone, but ended up talking to Deputy Attorney General Rod Rosenstein.
Ultimately, Flake stopped short of where Democrats hoped he would land, which was putting a hold on a committee vote. Instead, he wanted the one-week delay on a final vote on Kavanaugh's confirmation while allowing the nomination to move out of committee to the full Senate
