NBC reports there's a fourth allegation against Kavanaugh - from an anonymous accuser

NBC News says they have obtained a letter of a fourth allegation against Brett Kavanaugh, the Supreme Court nominee, from an anonymous source that contacted the Senate Judiciary Committee.

"They were all shocked"

According to the report, the accuser claims that Kavanaugh pressed her against a wall in an aggressive and sexual manner. She says that the assault allegedly happened after she had been socializing with him at a bar.

"When they left the bar (under the influence of alcohol) they were all shocked when Brett Kavanaugh," the letter read, "shoved her friend up against the wall very aggressively and sexually."

The writer of the letter provided no names, and said the victim wished to remain anonymous.

“There were at least four witnesses including my daughter," they wrote.

The assault allegedly occurred in 1998. The anonymous complaint was sent to Senator Cory Gardner (R-Col.).

These would be the fourth in a series of allegations against President Donald Trump's nomination to the Supreme Court. Kavanaugh has denied all the allegations and said that although he had attended parties where he drank too much, he was never witness to any events of the kind described in the claims.

"This is ridiculous and from the Twilight Zone," Kavanaugh said of salacious claims made by an accuser represented by Michael Avenatti.

In a long news conference Wednesday, the president defended his nominee, and said that his character was being unfairly smeared by Democrats and the media. However, he said that if the accusations were true that he would consider rescinding the nomination.

Republicans have scheduled a vote for confirmation on Friday morning.
