Chad Ludington, who went to Yale with Supreme Court nominee Brett Kavanaugh, said "there were omissions" in the nominee's testimony to the Senate Judiciary Committee on Thursday about his drinking in college.
He said that the altercation happened after a UB40 concert on September 25, when he and a group of people went to Demery's and were drinking pints.
His statement contradicts another Yale classmate - former National Basketball Association player Chris Dudley - who told the Washington Post he "never, ever saw Brett Kavanaugh black out" from alcohol consumption. Kavanaugh spoke to officers but did not want to say if "he threw the ice or not", according to the police memo.More news: US, Canada in last-minute NAFTA deal
Although the inquiry will focus on Ford's allegation against Kavanaugh, investigators are also examining claims made by another accuser, Deborah Ramirez, that Kavanaugh exposed himself to her at a dormitory party while the two attended Yale in the 1980s.
The man then swung at Kavanaugh and Dudley struck him with a bottle, Ludington said.
Ludington said he doesn't recall what Kavanaugh was doing as the fight erupted but police were called. The White House had no immediate comment when asked about Ludington's account, instead referring a reporter to statements issued earlier by Dudley and another classmate attesting to Kavanaugh's character.
On Monday, NBC News reported that the Federal Bureau of Investigation planned to talk with Ludington this week.More news: History shows us Ryder Cup isn’t over yet, says Europe captain Bjorn
Kavanaugh's drinking habits in high school and college were a topic of debate during last week's Senate hearing, where Dr. Christine Blasey-Ford, who accused the Supreme Court nominee of sexually assaulting her in high school, also testified. "Throwing ice 33 years ago, or her opinion of Judge Kavanaugh in July?" tweeted White House press secretary Sarah Huckabee Sanders. At one point, they were sitting near a man who, they thought, resembled Ali Campbell, the lead singer of UB40.
Noticing they were staring at him, the man aggressively told the quartet to stop, at which point Kavanaugh "threw his beer at the guy", Ludington said. Ludington said he believed Kavanaugh "mischaracterized the extent" of his drinking during the hearing.

A number of Kavanaugh's former classmates have said Kavanaugh's testimony before the Senate was misleading and omitted the true nature of his drinking habits.More news: Champions League: Four Manchester United players miss training ahead of Valencia clash
