Imitating Ford, he added, "But I had one beer - that's the only thing I remember".
He also backed his nominee's performance on Thursday.
In his testimony, Kavanaugh vehemently denied Ford's claim.
He said it's important that senators had a chance to ask directly about what the FBI investigated, what evidence they collected and who they interviewed.
The White House - through press secretary Sarah Sanders and others - has dismissed all the allegations against him as old news that had been litigated during the campaign.
"I had one beer. Only 113 people have ever served on the Supreme Court, and I believe that we must do our level best to protect its sanctity". Ford claims Judge helped Kavanaugh lock her in the room and stood there in the room and watched Kavanaugh getting on top of Ford in the bed and groping her. Ford says they turned on loud music in the room so no one could hear her scream. He pledged that the Senate will be voting on Kavanaugh this week. That's a very, very hard standard. Following Ford's testimony, Kavanaugh offered an irate rebuttal, which the White House called "spectacular". "I never drank", Trump said.
The Democratic leader, Sen. After Trump's speech in MS, many followers think his early assumption that Dr. Ford is lying is inappropriate considering the investigation is still ongoing.
Members of the #MeToo movement have cast the Kavanaugh nomination as a test of how society treats women who accuse powerful men of sexual misconduct.
It marked the sharpest criticism by Mr Trump of Ms Ford since she came forward publicly with the allegation last month. She concludes no prosecutor would bring the case, nor is the evidence sufficient to prevail even in a civil trial.
Writing to the FBI, attorneys for Professor Christine Blasey Ford said it was "inconceivable" that the agency could conduct a thorough investigation without interviewing her.More news: Indonesia seeks global help after quake-tsunami, mass prison breaks confirmed

Kavanaugh and Judge have denied the accusations. In fact, she spoke softly but emotionally and engaged thoroughly with her questioner.
The audience in Southaven laughed as Trump mimicked Ford answering questions on her alleged sexual assault.
His critics have expressed concern that he lied about his drinking habits.
Chad Ludington, who attended Yale with Kavanaugh and now teaches history at North Carolina State University, described the young Kavanaugh as a "frequent drinker, and a heavy drinker" who often became belligerent while drunk. I don't remember. How many years ago was it? "When Brett got drunk, he was often belligerent and aggressive", Ludington said.
The fight over Kavanaugh's nomination to a lifetime job on the top USA court comes against the backdrop of the #MeToo movement fighting sexual harassment and assault that has toppled a succession of powerful men.
Kavanaugh's confirmation continues to hang in the balance as the FBI investigates the allegation, which Kavanaugh has forcefully denied. For both the judge, and the nation, the stakes are high: If confirmed, Kavanaugh would replace retired Justice Anthony M. Kennedy, the swing vote on a deeply divided court.
Mr Trump's remarks came as he reiterated his support for Supreme Court nominee Brett Kavanaugh, who is now facing sexual misconduct allegations by several women.
"The FBI will do a supplemental background investigation, then I'm going to call for an investigation of what happened in this committee. And that should be the scope of it", Graham said on ABC's "This Week".
Sen. Tom Cotton (R-AR) said Sunday that Sen. Trump has accused Democrats of unfairly trying to derail Kavanaugh's nomination.
Republicans have 51 seats in the closely divided 100-member Senate and can not afford to lose more than one vote on confirmation. A third woman who has accused the judge of sexual misconduct in the 1980s, Julie Swetnick, was not on the initial list of witnesses to be interviewed.
