Ford, through her lawyers, called for an FBI investigation into her allegation prior to a public hearing. Other Democrats on the committee have made the same request, which would likely slow Kavanaugh's nomination proceedings to a crawl — a situation Republicans are eager to avoid, as the November midterm elections loom large.
In another statement released Wednesday evening, lawyer Lisa Banks said that "there are multiple witnesses whose names have appeared publicly and should be included in any proceeding."
Banks added: "The rush to a hearing is unnecessary, and contrary to the Committee discovering the truth."
Kavanaugh has strongly denied Ford's allegation, saying he would be willing to testify once again before the Judiciary Committee.
Grassley had originally said he would try to set up phone calls to question both Ford and Kavanaugh, but said California Democratic Sen. Dianne Feinstein's office refused to cooperate. He has since relented on that request and scheduled a hearing for 10 a.m. on Monday.
Ford wrote a letter detailing her allegation that was received by Feinstein in late July, but it was not publicly reported until mid-September. That letter alleges a very drunk Kavanaugh, with participation from his friend Mark Judge, held Ford down on a bed, covered her mouth to stifle her screams and attempted to take her clothes off.
Judge has said he has no recollection of the incident Ford described.
Sen. Susan Collins, R-Maine, said Wednesday that "both of them need to testify under oath next Monday."
"I think it's not fair to Judge Kavanaugh for her not to come forward and testify," she added.
Collins, who is widely viewed as a crucial swing vote on Kavanaugh's nomination, was among the first GOP senators to call for a public hearing.
Grassley's letter Wednesday also appeared to place the onus for an FBI probe on the president's shoulders.
"We have no power to commandeer an Executive Branch agency into conducting our due diligence," the letter said.
