He said he'd never done anything like the episodes his accusers have described and said he didn't have sexual intercourse until "many years" after high school. "And they debase our public discourse", Kavanaugh wrote.
Democrats are demanding a delay in Thursday's hearing before a Senate panel in which Kavanaugh's original accuser, Christine Blasey Ford, is scheduled to testify, along with Kavanaugh himself. But lately, he has expressed his frustrations on Twitter. "Innocent until proven guilty is how we do this in America".
Sitting beside his wife, Ashley Estes Kavanaugh - her first appearance since the allegations surfaced - the judge was given free rein to deny accusations that have now been leveled against him by two named women in addition to a third whose identity and detailed claims still remain elusive.
Sen. Orrin Hatch, R-Utah, a member of the Judiciary Committee, referred to Ramirez's allegation as "phony", and when pressed on why he characterized it that way, Hatch responded: "Because I know it is".
One Republican close to Kavanaugh's confirmation process who wasn't authorized to speak on the record, said "there's resolve in the White House". "There's a hearing on Thursday", she said. "I will not be intimidated into withdrawing from this process", Kavanaugh said in the letter. If elevated to the high court, the legitimacy of everything Judge Kavanaugh touches will be questioned. Go ahead and ruin this guy's life based on an accusation - I don't know when it happened, I don't know where it happened and everybody named in regard to being there, said it didn't happen. "We're talking about an allegation of sexual assault and I never sexually assaulted anyone", he added.
"There is no barrier to them doing it themselves", he said. "But I think she's sincerely wrong".
They want the FBI to reopen its background investigation of Judge Kavanaugh and look into the allegations against him.
Lawyer Michael Avenatti said he was representing a woman with information about high school-era parties attended by Kavanaugh and urged the Senate to investigate.
"Following Dr Ford's testimony, Judge Kavanaugh will appear again before the committee", the committee said in a statement. "This is a very dynamic situation".
The hearing will start at 10 a.m. and will be open to the public, the source said. He declined to provide more details.More news: The China-US Trade War Might Go Beyond Tariffs Soon

President Donald Trump was told about the new sexual misconduct allegations about Brett Kavanaugh in the New Yorker hours before the explosive publication Sunday, according to a White House official. "In my opinion, it's totally political".
"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", the statement read.
Republicans stepped up their attempts to discredit Ford's story.
She said on CBS "This Morning" that the allegations against Kavanaugh, now by a second woman, sound like a "vast left-wing conspiracy".
The new allegations raised broader questions about a nominee whose confirmation seemed all but certain two weeks ago.
Kavanaugh was nominated by President Trump in July to replace the vacancy left by Justice Anthony Kennedy, who retired.
For Trump, getting the conservative Kavanaugh into the lifetime appointment would cement his mission to shift the court to the right for years to come.
The second claim against Mr Kavanaugh dates to the 1983-84 academic year, which was his first at Yale University.
The allegations, dating back to the 1980s, have put in jeopardy Kavanaugh's chances of winning confirmation to the top US court in a Senate narrowly controlled by Trump's party, with high-stakes congressional elections just weeks away.
Trump, himself accused during the 2016 presidential race of sexual misconduct with numerous women, twice offered words of support for Kavanaugh while in NY to attend the U.N. General Assembly. "Judiciary staff reached out to our office and asked for a connection to someone who might be helpful should Deborah Ramirez decide to come forward with an allegation related to that made by Dr. Ford".
