The spokesperson in a statement slammed Democrats for "withholding information" regarding the allegations.

"Yet again, Senate Democrats actively withheld information from the rest of the Committee only to drop information at politically opportune moments," the statement said, doubling down on his remarks that Democrats withheld the first allegation against Kavanaugh from Christine Blasey Ford, who went public last week.

The spokesperson said the Democrats appear to be "more interested in a political takedown" than "pursuing allegations through a bipartisan and professional" investigation.

"Of course, we will attempt to evaluate these new claims," the statement added.

Deborah Ramirez in a New Yorker report alleged that Kavanaugh exposed himself without her consent during a Yale University gathering in the 1980s, when they were both students. She said he thrusted his penis in her face, forcing her to touch it when she pushed him away.

Kavanaugh denied the accusation, and the White House in a statement said it stands behind President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'

GOP staffers knew that the Ramirez accusation were forthcoming as they pushed to move the nomination process ahead last week, according to The New Yorker. Grassley denied this, saying the committee's staff was not aware until Sunday.

"The committee’s majority staff learned the allegations made by Deborah Ramirez about Judge Kavanaugh from this evening’s New Yorker report," Grassley's spokesperson said. "Neither she nor her legal representative have contacted the chairman’s office. The article reports that Democratic staff were aware of these allegations, but they never informed Republican staff."

"No, Senate Democrats didn’t inform us of these allegations," Antonia Ferrier tweeted on Sunday night.

Michael Avenatti, the lawyer representing adult-film actress Stormy Daniels, on Sunday tweeted an email sent to Mike Davis, the chief counsel for nominations for the Senate Judiciary Committee, in which he claimed he has evidence that Kavanaugh engaged in "the targeting of women with alcohol/drugs to allow a ‘train’ of men to subsequently gang rape them.”

"There are multiple witnesses that will corroborate these facts and each of them must be called to testify publicly,” Avenatti wrote.

Grassley's spokesperson said the committee has asked Avenatti to provide the evidence.

"Shortly after Mr. Avenatti announced that he may have information pertinent to the committee’s consideration of the Supreme Court nomination, the chairman’s office emailed him directly to request any relevant information he might have," the statement said. "Mr. Avenatti publicly Tweeted his response to committee staff. The committee staff requested that Mr. Avenatti provide any evidence that he claims to have."
