WASHINGTON - A childhood friend of Supreme Court nominee Brett Kavanaugh says he will cooperate with an FBI investigation or any law enforcement investigation that is done "confidentially to investigate" numerous claims of sexual assault.

Mark Judge has seemingly found himself at the center of the Supreme Court debate. He is the man accused of watching and laughing while Kavanaugh, his classmate and close friend Kavanaugh, held a girl down and tried to remove her clothes at a party while they were all in high school.

Both Judge and Kavanaugh have denied both Ford's allegations and those by a handful of other women.

"I will cooperate with any law enforcement agency that is assigned to confidentially investigate these allegations," a signed letter by Judge states.

The letter was sent to leadership on the Senate Judiciary Committee Friday after a dramatic vote on the panel with Jeff Flake, R-AZ, a deciding vote for Republicans, saying he would only vote to confirm Kavanaugh to the high court after a week delay and FBI investigation.

In it, Judge states he does not know Julie Swetnick, the third woman who has come forward with sexual assault accusations against Kavanaugh. Swetnick also made a number of allegations against Judge and his actions in the 1980s.

"I do not recall attending parties during 1981-1983 when I fondled or grabbed women in an aggressive or unwanted manner," he wrote. "I have never spiked punch to get anyone drunk or disoriented."

He added: "I have never engaged in a gang rape of any woman, including Ms. Swetnick."

Since the allegations by psychology professor Christine Blasey Ford came to light, Judge left town and was spotted holed up in a Delaware beach house.

Over the last two weeks, Democrats and Ford's attorneys have repeatedly called for Judge to be subpoenaed and questioned him under oath about the batch of allegations by women describing Kavanaugh assaulting them and his alleged drunken behavior.

Judge has supplied a number of written statements to the Senate Judiciary Committee, including one Thursday evening after hearing Ford's emotional testimony before the panel.

"I did not ask to be involved in this matter nor did anyone ask me to be involved. We have told the Committee that I do not want to comment about these events publicly," he said, adding "I do not recall the events described by Dr. Ford in her testimony before the US Senate Judiciary Committee today. I never saw Brett act in the manner Dr. Ford describes."

The letter, and others he's submitted to the committee are sworn statements and come under the penalty of a felony. His comments to the FBI would carry a similar penatly.

Asked whether Ford will offer the FBI similar testimony that the allegations against Kavanaugh were false, his attorney, Barbara Van Gelder told USA TODAY "Mr. Judge will answer any and all questions that FBI wants to ask him."

Judge, an author and columnist, was placed under the national spotlight after Ford's allegations and his writings faced intense scrutiny.

His books, "Wasted: Tales of a Genx Drunk" and "God and Man at Georgetown Prep: How I Became a Catholic Despite 20 Years of Catholic Schooling," have been examined for their portrayal of a high school culture centered on binge drinking and chasing girls. And some of his columns from more recent years have been criticized for their takes on sex and women.
