Ramirez was initially "reluctant to characterize Kavanaugh's role in the alleged incident with certainty", according to the New Yorker, and she admitted to having gaps in her memories.
"Listen to Christine Blasey Ford", the statement concluded.
"Courageously Dr Ford will tell her story in the face of an impossible choice and vile bullying by the Republican leadership", said Senator Richard Blumenthal, a member of the Judiciary Committee.
On Saturday night, Leland Ingham Keyser, a classmate of Ford's at the all-girls school Holton-Arms and her final named witness, denied any recollection of attending a party with Brett Kavanaugh.
The White House said this could be a delaying tactic.
Kavanaugh has denied the accusation and called it a smear. "Judge Kavanaugh is an outstanding person and I am with him all the way".
Ford is claiming Kavanaugh sexually assaulted her when she was 15 and he was 17 during a teenage party when they were high school students in suburban Washington D.C.
US President Donald Trump has made a decision to stand behind his Supreme Court nominee Brett Kavanaugh.
Her allegation against the conservative federal appeals court judge has endangered his confirmation by the Republican-led Senate to a lifetime job on the top US court.
He's also denied new accusations by a woman who says he exposed himself to her while they were students at Yale. Ford and Kavanaugh are expected to testify on Thursday.
"This is a smear, plain and simple", Kavanaugh said.
Earlier, Senator Lindsey Graham, a South Carolina Republican on the Senate Judiciary Committee, said lawyers for Ms Ford were contesting two GOP conditions - that Ms Ford and Mr Kavanaugh would be the only witnesses and that an independent counsel would ask the questions.
Ramirez told the magazine she had become inebriated during a drinking game and was on the floor when the alleged incident took place.
Kellyanne Conway says the country shouldn't make Supreme Court nominee Brett Kavanaugh pay for "pent-up" demand by women incensed about sexual misconduct.
Senate Democrats are now investigating a bombshell claim by Deborah Ramirez, 53, who says Kavanaugh exposed himself to her during a 1980s college party at Yale University, thrust his genitals in her face and caused her to touch them without her consent, according to The New Yorker.
Whelan apologized for publicly naming Kavanaugh's former classmate and suggesting he may have assaulted Ford. "We have to do a lot of listening both to Judge Kavanaugh and my constituent". "But she can come and tell that story".
"Despite actual threats to her safety and her life, Dr. Ford believes it is important for senators to hear directly from her about the sexual assault committed against her", Ford's attorneys Debra Katz, Lisa Banks and Michael Bromwich said in a statement.
Kavanaugh told the magazine in a statement that the newly alleged event from 35 years ago "did not happen".
Judiciary Committee Chairman Chuck Grassley, a Republican, had set several deadlines since Friday for Ford to decide whether and how she would testify before the panel.
Mr Grassley turned down Ms Ford's request that only senators, not lawyers, be allowed to ask questions.
Trump said that he would not likely be able to convince Democrats to vote for Kavanaugh, which means he would need the support of nearly every Republican in the Senate.
