The deal comes after days of intense negotiations in which Ford's attorneys sought to push back a hearing that Grassley initially tried to schedule for Monday, while she and Democrats asked that the FBI launch an investigation into her claims.
The claim dates to the 1983-84 academic school year, when Kavanaugh was a freshman at Yale University.
Aside from all that, the Kavanaugh team thought his 1982 calendars were significant enough leak to the New York Times before submitting them in a Congressional hearing, and the reason for that significance is that they don't include any specific reference to the specific details of a party which has never been definitively placed in time and space.
"I want to listen to her, but I'm being honest with you and everybody else".
Kavanaugh, who strongly denies the assault allegation, has said he wishes to testify as soon as possible to clear his name.
The depths to which Kavanaugh's defenders are willing to sink was underscored when Ed Whelan, the president of the Ethics and Public Policy Center, sent out a tweet thread pushing a mistaken-identity alibi to explain away Ford's allegations against Kavanaugh.
"This 35-year-old, uncorroborated claim is the latest in a coordinated smear campaign by the Democrats created to tear down a good man", said WH spokesperson Kerri Kupex. FiveThirtyEight points out, "Grassley and the White House have already said they are standing behind Kavanaugh".
She told the publication she remembered Kavanaugh was stood to her right and recalled him pulling up his trousers while he and other students laughed.
Dianne Feinstein, the top Democrat on the Judiciary Committee, immediately called for a postponement of Kavanaugh's nomination and called for the FBI to investigate both Ford and Ramirez's allegations. The people who knew me then know that this did not happen, and have said so.
Lawyers for Ford earlier said Ford would testify only if her safety is ensured.
A public hearing would be a high-stakes confrontation echoing the 1991 event when Anita Hill accused now-Supreme Court Justice Clarence Thomas of sexually harassing her when he was her supervisor at two federal agencies.
In a statement late Saturday, the White House addressed the specifics of Ford's case: it said the four other people Ford claimed were at the party where the incident allegedly occurred all denied "any knowledge of the incident or having attended such a party".
"This is totally untoward because remember, during the Anita Hill days there was an investigation, perfunctory as that was, but Dr. Ford is not even afforded that", Hirono told Jake Tapper. The counsel said it was the committee's "non-negotiable" right to determine who would be allowed to testify.
"We committed to moving forward with an open hearing on Thursday September 27 at 10am". The committee's 11 Republicans - all men - have been seeking an outside female attorney to interrogate Ford, mindful of the election-season impression that could be left by men trying to pick apart a woman's assertion of a sexual attack.
Lindsey Graham - a member of the Senate Judiciary Committee that must approve Kavanaugh's nomination before it goes to the full chamber - summed up the position of many Republicans by saying he did not expect Ford's testimony to change his mind.
The New Yorker was not able to confirm with other eyewitnesses that Kavanaugh was present at the party, but at least one person - who declined to be named - said he was told about the incident and "one hundred percent sure" it involved the judge.
