Brett Kavanaugh is not a 'stumbling, bumbling drunk' and is no Bill Cosby, Lindsey Graham says

Brett Kavanaugh is no Bill Cosby, Lindsey Graham says.

The Republican senator dropped the convicted comedian's name on Sunday as he told ABC's "This Week" that there was no need for the FBI to dig deep into the Supreme Court nominee's drinking habits.

"No, I think you're trying to portray him as a stumbling, bumbling drunk, gang rapist, who during high school and college was Bill Cosby," Graham told George Stephanopoulos. "Six background checks over the years would have uncovered this."

Cosby was sentenced to three to 10 years in prison earlier this week for sexual assault, and he has been accused of misconduct by dozens of women.

Kavanaugh, accused of sexually assaulting Christine Blasey Ford at a high school party in 1982, told the Senate Judiciary Committee on Thursday that he liked beer but never blacked out from drinking, and highlighted his strong academic and athletic performance.

A former Yale classmate of Kavanaugh's told ABC's "Good Morning America" that good grades and partying "are not mutually exclusive."

"I also was an athlete at Yale ... I went on to Wharton Business School, and I drank in excess many nights with Brett Kavanaugh," Lynne Brookes told ABC News. "So he was trying to portray that it's one or the other and at Yale ... there’s a lot of people for which that was both."

When pressed by Stephanopoulos about the drinking allegations, Graham said: "He's had six FBI background checks. He's been on the political stage for 26 years. He's not a stumbling, bumbling drunk. I don't believe that you could accomplish what he's accomplished to have been a serial rapist in high school."

Multiple woman have accused Kavanaugh of sexual misconduct dating back to when he was a student. President Trump on Friday appeased Democrats by ordering the FBI to open an investigation into the allegations against Kavanaugh after Ford had testified that she was "100%" sure that she was assaulted by Kavanaugh.

The FBI probe will be "limited to current credible allegations" against Kavanaugh. Graham told ABC News that he believes the agency will speak to people that Ford said were at the party where the alleged assault took place.

The 53-year-old Kavanaugh has denied all the accusations made against him by Ford and the other women and alleged a political conspiracy against him by the Democrats.

Graham, the senator from South Carolina, said there will be an investigation into how Ford's original letter was leaked to the press.

“We're going to do a wholesale, full-scale investigation of what I think was a despicable process to deter it from happening again,” Graham told ABC News.
