If the FBI does its job in this instance they will look at the statements Kavanaugh made in last week's hearing, try to coorborate Kavanaugh's interpretations with those of his high school mates, deliver those findings to the Judiciary Committee, and let those senators use the same standard Kavanaugh's own mother used as a Justice:

"There is a chance the FBI might uncover additional evidence or testimony that further corroborates these women’s claims. But if not—especially as reports suggest that the White House is narrowing the scope of the probe and hamstringing investigators’ ability to get to the truth of these allegations—the FBI still must examine Kavanaugh’s credibility and candor.
FBI agents will not provide a conclusion or judgment about Kavanaugh’s credibility, but they can—and must—look to his Senate testimony and present senators with evidence that refutes or corroborates it.
For example, FBI investigators should ask Kavanaugh’s football teammates—many of whom also dubbed themselves “Renate alumni” in their own yearbook entries—exactly what the reference meant. They should ask Kavanaugh’s friend Mark Judge, whose yearbook entry also referenced boofing, if he agrees—under oath—that it means what Kavanaugh said it does. They should find the friends who supposedly played Devil’s Triangle with Kavanaugh.
Regardless of whether such petty lies could ever amount to perjury, they provide glimpses into Kavanaugh’s character and candor. As Kavanaugh well knows, in our legal system, even small lies matter. In jury trials, there is a standard instruction to jurors that if they conclude a witness is lying about any matter, they have the right to dismiss that witness’ entire testimony as potentially untruthful.
Kavanaugh’s own mother was a judge, and he has described her judicial philosophy as this: “Use your common sense, what rings true, what rings false.”
Senators weighing Kavanaugh’s fate should apply the same standard. To date, many of them have tried to dismiss Ford’s allegations as a case of “he said, she said.” But any proof that Kavanaugh lied under oath should cause senators to err on the side of believing her over him.
Furthermore, anyone prone to such casual lying is not fit to serve a lifetime appointment on the nation’s highest court.
After all, if Kavanaugh can’t be trusted to tell the truth about even the minor stuff, why should we trust him on anything else?"
