Another of Supreme Court nominee Brett Kavanaugh's former Yale University classmates is accusing him of propagating a “blatant mischaracterization” of his college drinking habits before the Senate Judiciary Committee, according to multiple reports.

Charles "Chad" Ludington, a North Carolina State University associate professor who used to interact with Kavanaugh while the two were at Yale, told the Washington Post and New York Times Sunday the judge had been untruthful when he told the panel last week he had never "blacked out" because he frequently saw Kavanaugh “staggering from alcohol consumption.”

"When Brett got drunk, he was often belligerent and aggressive," Ludington said in a statement to the Washington Post. "On one of the last occasions I purposely socialized with Brett, I witnessed him respond to a semi-hostile remark, not by defusing the situation, but by throwing his beer in the man’s face and starting a fight that ended with one of our mutual friends in jail."

Ludington, who the New York Times reported has made donated small amounts of money to Democratic candidates, plans to provide a statement to the FBI's field office in Raleigh, N.C., on Monday.

"I do not believe that the heavy drinking or even loutish behavior of an 18 or even 21 year old should condemn a person for the rest of his life,” Ludington told the Post. “However ... if he lied about his past actions on national television, and more especially while speaking under oath in front of the United States Senate, I believe those lies should have consequences.”

James Roche, one of Kavanaugh's freshman roommates, also described the judge last week as aggressive and belligerent when he drank.

The FBI investigation has been criticized by Democrats for reportedly only targeting four people as part of a supplemental background investigation, authorized by President Trump, into the sexual misconduct allegations leveled against Kavanaugh. The White House has denied limiting the scope of the probe.

The full Senate will not vote on Kavanaugh's confirmation until the FBI's inquiry is tentatively completed within the week.
