Beth Wilkinson, who is Kavanaugh's attorney, is interested in seeing the therapy sessions notes, which she says are important to corroborate claims made by Ford.
Norman Ornstein, who studies politics and Congress at the American Enterprise Institute in Washington, said the Republicans could suffer a political defeat if Ford proves to be a persuasive witness in the glare of the nationally televised hearing on Thursday.
The woman who was allegedly shoved has remained anonymous and is reportedly still traumatized by the incident.
After being alerted to the new allegation, Senate Judiciary Committee staffers called Kavanaugh on Tuesday, to question his involvement in the incident, at which time the prospective Supreme Court Justice denied even associating with a Boulder woman at the time.
Kavanaugh vehemently denied the allegations to investigators on the call.
"We're dealing with an anonymous letter about an anonymous person and an anonymous friend".
"This is ridiculous and from the Twilight Zone", he said in a statement.
"We did not know each other well, but I knew him and he knew me", she says.
The committee late Wednesday said it had interviewed two men who said they, and not Kavanaugh, had the encounter with Ford that she describes.
Another woman came forward over the weekend, telling The New Yorker magazine that Kavanaugh exposed himself and caused her to touch his penis at a party when both were Yale freshmen.
Swetnick is represented by lawyer Michael Avenatti, who also represents adult film star Stormy Daniels in a lawsuit against Trump to void a nondisclosure agreement under which the president's former personal lawyer paid her $130,000 not to discuss her alleged relationship with Trump years ago.
In a sworn statement, she said she witnessed Kavanaugh "consistently engage in excessive drinking and inappropriate contact of a sexual nature with women in the early 1980s".
"I heard Brett and Mark leave the bedroom laughing and loudly walk down the narrow stairs, pin-balling off the walls on the way down", she said.
In the past month, three women have publicly accused Kavanaugh of sexual misconduct.
"When you are guilty until proven innocent, it's just not supposed to be that way", Trump said.
Ford has claimed that Kavanaugh tried to remove her clothes and clamped a hand over her mouth at a party when both were in high school.
"It's happened to me many times". President Donald Trump has cast skepticism on her story, saying it's part of a Democratic con job, but he also said he's open to changing his mind.
Blasey Ford said she was finally able to escape and rushed out of the house with an "enormous sense of relief" that the teens did not follow her.
Then a letter by psychologist and statistics professor Doctor Christine Blasey Ford emerged making claims of sexual assault against him. The author wrote that in 1998 her daughter occasionally socialized with Kavanaugh, who was dating the daughter's friend while he was an attorney working on independent counsel Kenneth Starr's investigation into the Clinton White House.
"I think this is this is insane town", he added.
