At a political rally in Mississippi on Tuesday night, Mr Trump mimicked Ms Ford's responses at a Senate Judiciary Committee hearing last week at which she recounted Mr Kavanaugh's alleged attack on her when both were in high school.
Ford said she didn't remember some details but that others were "seared into [her] memory".
During an interview on Wednesday at The Atlantic Festival, Republican Sen.
"He sent a clear message to victims of sexual assault that they should not be believed", Feinstein said in a statement released early Wednesday afternoon. One read: "At an event in Mississippi, President Ford mocked the woman who accused Judge Brett M. Kavanaugh of sexual assault".
Ford said Judge Kavanaugh, 53, assaulted her when they were teenagers.
That "is going to depend on what comes back from the FBI", Trump said.
The first thing to note: One would normally assume that Ford's interactions with her psychotherapist are confidential and protected from disclosure. Kavanaugh has denied Ramirez's allegations.
The assessments of Collins and Flake, the Judiciary Committee member who pushed to delay the vote on Kavanaugh so the FBI could investigate, came the morning after Trump drew laughs for his remarks at a political rally in Mississippi. "And I think there have been many occasions when you don't state the facts".
CNN reported late Tuesday that the FBI has actually widened the scope of its investigation, adding a specific party from Kavanaugh's calendar to its inquiry. 'I don't know.' Where's the house?

The measures in the new deal - which Mr Trump dubbed "US MCA" - "will support many - hundreds of thousands - American jobs". President Trump weighed in on the name during a Monday press conference, saying, "It has a good ring to it".
Flake didn't say whether he'll vote to confirm Kavanaugh to the Supreme Court.
In a separate statement on Twitter, John Clune, who represents another accuser, Deborah Ramirez, said Federal Bureau of Investigation agents interviewed her on Sunday and accepted a list of more than 20 witnesses who can support her allegations.
Sen. Joni Ernst, R-Iowa, said Ford's story hasn't been corroborated and people should be presumed innocent until proved guilty.
Arizona Republican Senator Jeff Flake said that mocking "something this sensitive at a political rally is just not right".
On Friday, Trump authorized a FBI investigation into the allegations against his Supreme Court nominee with a deadline of one week.
Senators Flake, Collins and Murkowski are potential swing voters on Mr Kavanaugh's confirmation. Prof Ford alleges that Mr Judge also took part in the assault at a high school party in 1982.
Trump openly mocked Ford at a campaign rally, pointing to what he presented as holes in her testimony.
Although the FBI has yet to conclude its investigation, Senate Majority Leader Mitch McConnell vowed Tuesday that a vote will happen on Kavanaugh's nomination this week regardless of what the FBI finds.
Sanders also defended Kavanaugh, saying that throughout the confirmation process, every single word of Kavanaugh's has been picked apart "while if anybody says anything about these accusations, that's totally off limits and outrageous".
