SENATE VOTES TO ADVANCE KAVANAUGH NOMINATION, SETTING UP FINAL VOTE FOR SATURDAY

Police announced the arrests hours after Sens. Susan Collins, R-Maine, and Joe Manchin, D-W.Va – both considered key lawmakers needed to confirm Kavanaugh – announced that they intended to vote in favor of his appointment to the Supreme Court.

Kavanaugh’s nomination to the nation’s highest court has become particularly controversial in recent weeks after three women come forward with allegations of sexual misconduct. The first accusation came from Christine Blasey Ford, who claimed Kavanaugh assaulted her at a party in high school.

Kavanaugh has vehemently disputed the allegations made against him.

A final confirmation vote on his nomination is scheduled for Saturday afternoon.
