A Yale classmate of Brett Kavanaugh's claims the Supreme Court nominee lied about his drinking habits in college during his Thursday hearing.

'I like beer, I still like beer,' Kavanaugh testified under oath in front of the Senate Judiciary Committee. 'But I did not drink beer to the point of blacking out, and I never sexually assaulted anyone.'

But Lynne Brookes tells ABC News that she recalls his drinking habits as much more extreme than what Kavanaugh conveyed during his hearing.

Brookes, a registered Republican in Pennsylvania, said she was in the 'exact same social circles' as the embroiled judge while they both attended Yale and he 'mischaracterized himself' when describing his drinking habits Thursday.

'From something I witnessed personally,' Brookes said. 'I find it very hard to imagine that he never blacked out or had memory problems.'

Lynne Brookes says she was in the 'same social circles' as Kavanaugh at Yale and he drank in excess

The Supreme Court nominee claimed under oath on Thursday that he never drank in excess or blacked out

During Dr Christine Blasey Ford's portion of the hearing, she explained how she feared for her life when a 'visibly drunk' Kavanaugh sexually attacked her at a high school party when she was 15.

Brookes noted she is a registered Republican - not part of left wing conspiracy - said Kavanaugh 'mischaracterized himself' under oath during his hearing

Following her testimony, Kavanaugh denied ever sexually assaulting Ford but repeatedly evaded questions about his drinking in high school and college.

When asked by Minnesota Senator Amy Klobuchar whether he had ever drank so much that he lost memory, Kavanaugh deflected, saying: 'No, I remember what happened. And I think you've probably had beers, Senator.'

Brookes told CNN that she and other Yale colleges were 'extremely disappointed' at the way Kavanaugh 'evaded' his excessive drinking questions.

She further added that Kavanaugh misrepresented students' ability to balance school work and social life at Yale.

'He was trying to portray that it's one or the other, and at Yale there are many people for which it was both,' she said. 'I played two sports. I got good grades. I went to Wharton. And I drank in excess many nights with Brett Kavanaugh.'

'When he would drink, he would get obnoxious,' she added.

Brookes recalled her most specific memory of Kavanaugh - when he was pledging to a fraternity.

'Brett was getting tapped in and he was incredibly drunk, in a ridiculous outfit and had to come up to me and sing a silly song,' she said.

'He was so incredibly drunk. I find it not plausible at all that he remembers everything he did that night.'

However, Brookes, who was roommates with another Kavanaugh accuser Deborah Ramirez, said she never felt unsafe around the judge nor did she witness any of the sexual abuse claims made against him.

Though Kavanaugh did admit at one point that he may have 'had too many' beers on occasion, he denied 'blacking out' and vehemently denies the sexual abuse.

'There were a lot of emails and a lot of texts flying around about how he was lying to the Senate Judiciary Committee,' Brookes said of messages sent between her and her Yale colleagues as the hearing went on.

'I'm not part of some left wing conspiracy,' she said, adding that she is registered Republican.

'This is about the integrity of the Supreme Court,' she said. 'I know that Brett mischaracterized himself, and it's incredibly disappointing that despite that this man could be elevated to the Supreme Court.'
