Guy Benson called out Democrats for immediately running with Julie Swetnick's uncorroborated, lurid rape allegations against Supreme Court nominee Brett Kavanaugh.

Swetnick, who is represented by anti-Trump attorney Michael Avenatti, initially claimed that Kavanaugh had been involved in drugging and gang-raping young women at high school parties in the 1980s.

In an interview with NBC News journalist Kate Snow, however, Swetnick appeared to walk back some of her claims.

Swetnick said that she saw Kavanaugh "paw on girls" and "[touch] them in private parts" at parties as a high school student, but stopped short of claiming that he drugged or sexually assaulted her or other women.

On "America's Newsroom" Tuesday, Benson said Swetnick "totally changed" her story in the interview.

He pointed out that Swetnick originally claimed that she saw Kavanaugh and his friends spike the punch at parties with drugs, but she amended that in the NBC interview, only saying that she saw Kavanaugh near the punch.

"Before the hearing with Dr. [Christine Blasey] Ford on Thursday, on Wednesday this Avenatti bomb gets dropped and all Democrats on the [Senate] Judiciary Committee validated it by reacting to it with an official letter calling on Kavanaugh to withdraw, based on a story that they knew nothing about," Benson said.

He said the more we learn about Swetnick's story, the more it looks like a "complete ludicrous hoax."

In a "Hannity" interview Tuesday, Sen. Lindsey Graham (R-S.C.) blasted NBC News for its coverage of the Kavanaugh allegations, calling the news organization a "co-conspirator" in trying to destroy his reputation.
