Kavanaugh's drinking history, which has come up in the allegations, is not part of the probe being managed by the FBI's security division at the agency's headquarters in Washington, the source said.
The classmate, Chad Ludington, who said he frequently socialized with Kavanaugh as a student, said in a statement that the judge had been untruthful in testimony to the Senate Judiciary Committee when he had denied any possibility that he had ever blacked out from drinking.
The FBI has begun investigating allegations of sexual misconduct by an intoxicated Kavanaugh in high school and college, allegations the appeals court judge flatly denies.
On Friday, Republican Sen.
The Senate Judiciary Committee recommended on Friday that the full Senate confirm Kavanaugh, who has aggressively denied the allegations.
US President Donald Trump has turned the fight over the nomination of Judge Brett Kavanaugh to the Supreme Court into a midterm election rallying cry, denouncing "the ruthless and outrageous tactics of the Democrat Party". "Whatever that means, according to the senators and the Republicans and the Republican majority, I want them to do that", Trump said at a White House news conference, although he added that "I'd like it to go quickly".More news: Google's YouTube Said to Be Hosting Videos on 'How to Hack Facebook'
He said the process was "so bad for our country" and said the questioning of Kavanaugh by Democrats on Thursday was a "disgrace".
"A "he said, she said" case is incredibly hard to prove, but this case is even weaker than that", Rachel Mitchell wrote in a five-page memo sent to all Senate Republicans Sunday night and obtained by The Washington Post.
Avenatti added: "Trump has now determined that he and he alone will be the sole arbiter of whether a woman's claims of sexual assault and misogyny are credible".
Trump also says he thinks Kavanaugh spoke "very conclusively" and "very well" during his testimony last week, but says he was surprised by how vocal Kavanaugh was describing his alcohol use and how much he likes beer.

Carl Tobias, a law professor at the University of Richmond, said it would not be unlawful for the White House to restrict the investigation's scope because the FBI is under the executive branch.
The poll, released on Sunday, follows an emotionally charged week in Washington, during which Kavanaugh's once-certain confirmation was jeopardized after three women made allegations against him, including accusations of assault and exposing himself in public in the 1980s.
Kavanaugh has strongly denied the allegations, but the Senate directed the FBI to investigate them for up to a week.
It did not take long, however, for the Federal Bureau of Investigation probe to become an object of partisan division.
Mitchell is a Phoenix-based sex crimes prosecutor Republicans hired to question Christine Blasey Ford about her claims against Kavanaugh during a Senate Judiciary Committee hearing last week. He also says Kavanaugh was often belligerent and aggressive when drunk. The full Senate was scheduled to vote Tuesday on Kavanaugh, who now sits on the District of Columbia Circuit Court of Appeals, though that could be scuttled if a lengthier investigation is launched into the allegations against him.More news: Elon Musk’s "Funding Secured" Tweet Just Cost Him & Tesla $40 Million
