Kavanaugh has repeatedly denied the allegations.
Senator Chris Coons (D-Del), called Trump's comments "unacceptable and beneath the Presidency of the United States". So Trump instead trained his fire on the top Democrat on the judiciary panel, Senator Dianne Feinstein of California, who waited until last week to disclose the existence of a letter Blasey had sent in late July.
Susan Collins said she was "appalled" by President Trump's tweets Friday morning that criticized Christine Blasey Ford for not coming forward sooner with her allegations against Supreme Court nominee Brett Kavanaugh. President Trump has also raised doubts about Ford's credibility, asking on Friday why she did not reveal her story earlier. "She should've reported to it to the police".
The protesters chanted, in part: "We believe Christine Ford!"
Grassley consented to other Ford demands, including that she be provided security and that Kavanaugh not be in the hearing room when she testifies. Team Ford could meet his ultimatum by providing a response before 10:00 p.m.in which she did not decline to testify. She said she revealed the incident to her husband and therapist at a 2012 couple's therapy session.
The choice of a new justice for the Supreme Court is pivotal, as it often gives the final word on highly contentious laws and its nine judges have an vast impact on USA public life.
"It's certainly a motivating issue for people", he added.
The letter was leaked to the public without a name included within a week of the committee vote.
His Republican party accuses the Democrats of using Ford as a last-minute spoiler to try and wreck Kavanaugh's path to the highest court, where he would tilt the bench firmly to the right for possibly years to come.
Housing and Urban Development Secretary Ben Carson speaks to the 2018 Values Voter Summit in Washington, Sept. 21, 2018.
Democratic senators, pointing to the highly charged Anita Hill hearings in October 1991, have defended Ford's request to have the Federal Bureau of Investigation do its own probe before she testifies. "We've all made clear this is her chance". If it's true, and it happened, she is now being used as a political pawn.
The committee's Republicans proposed a Wednesday hearing on a sexual assault allegation against Mr Kavanaugh, a day earlier than his accuser is seeking, as both sides stepped up pressure over the terms of what would be explosive testimony.
Ford's accusations of Kavanaugh's behavior 35 years ago and the unusually tense standoff over the terms of her appearance have captivated the nation as the appellate court judge's confirmation to the court hangs in balance.
The summit, a gathering of conservatives who support "traditional marriage, religious liberty, sanctity of life and limited government", comes almost seven weeks ahead of the midterm elections, which will decide control of the House and Senate.
The Senate panel must approve Kavanaugh's confirmation before a vote by the full Senate, where Republicans hold a 51-49 majority.
White House officials remain confident Kavanaugh will be confirmed. Ford's lawyers had requested that she go second. "That will be determined in seven weeks".
Republican lawmakers are trying to win Senate confirmation for Kavanaugh ahead of the court's start of a new term on October 1, or if not by then, ahead of the November 6 nationwide congressional elections, to show Republican voters they have made good on campaign promises to place conservative judges like Kavanaugh on the Supreme Court. "We're not going to slow down". I will not forfeit my ability to question Judge Kavanaugh and anyone else who comes before the committee with testimony, no matter how uncomfortable it may make the 11 men across the dais. "You've watched the tactics", McConnell said at the Value Voters Summit in Washington.
Trisha Hope, of League City, Texas said of Kavanaugh: 'I think I've never seen such a spectacle in my life, to see Democrats act this way'.
