One key interview now finished in the probe of allegations against the Supreme Court nominee.

FOX's Rachel Sutherland reports from Washington:

Fox News has learned the FBI has spoken with Mark Judge, an old friend of Judge Kavanaugh's, whom Christine Blasey Ford claims was there the night she was sexually assaulted. This, as Senate Republicans move forward with Judge Kavanaugh's nomination this week.

Majority Leader Mitch McConnell calling on colleagues to reject the "politics of personal destruction":

(McConnell): "After the FBI shares what they've found, Senators will have the opportunity to vote."

Democrats want the FBI to interview around two dozen witnesses in the probe, which President Trump wants wrapped up by the end of the week.

In Washington, Rachel Sutherland, FOX News.
