Speaking to reporters at the White House on Tuesday, Mr Trump said: "My whole life I've heard, "you're innocent until proven guilty", but now you're guilty until proven innocent".
"What message that sends to women in America is that we are innocent until proven guilty in this country", said Ernst.
"My White House will do whatever the senators want", Trump said.
"[Democrats] will not be satisfied unless they have brought down Judge Kavanaugh's nomination", Republican Majority Leader Mitch McConnell of Kentucky said. Jeff Flake (R-Ariz.) and other lawmakers, the Senate last Friday agreed the FBI could investigate for up to a week, meaning its deadline is this Friday. She would not say if the remarks would affect her vote.
The fight over Kavanaugh's nomination has been unusually emotional and has unfolded just weeks ahead of November 6 elections in which Democrats are trying to seize control of Congress from Republicans. Some Republicans fear that pushing ahead with confirmation could alienate women voters, while Democrats seek to capitalize.
"What's happening here has much more to do than even the appointment of a Supreme Court justice".
"You could be somebody that was ideal your entire life and somebody could accuse you of something - doesn't necessarily have to be a woman - but somebody could accuse you of something and you're automatically guilty". "Women are very angry", Trump said.
Flake acknowledged on Monday that the incident, aired widely, helped lead to his request at the subsequent committee hearing that an Federal Bureau of Investigation probe be conducted before a full Senate vote on Kavanaugh.More news: Lana Del Rey calls out Kanye West over his support of Trump
"What neighbourhood was it in? Whatever that means, according to the senators and the Republicans and the Republican majority, I want them to do that", Trump said at a White House news conference. 'I don't know. Upstairs. But I had one beer.
"If his nomination were to fall short, I would encourage President Trump to re-nominate Judge Kavanaugh to the Supreme Court", Graham said in a statement.
Kavanaugh has denied claims of sexual misconduct by three different women - Ford, Deborah Ramirez and Julie Swetnick. Aside from Flake and Collins, all eyes also are on Republican Sen. I have it myself all the time. "We simply can't", Flake said at an event hosted by The Atlantic.
His comments come as Democrats are pressing for a more expansive FBI investigation into allegations of sexual misconduct by Kavanaugh.
"Your vote in this election will decide which party controls the United States Senate", Trump said. "'I don't know.' 'But I had one beer, that's the only thing I remember, '" the president said as the crowd cheered.
Republicans have accused Democrats of trying to drag out the confirmation process, with McConnell repeatedly charging they're trying to "move the goalposts".
John Kennedy, who sits on the judiciary committee, said that Swetnick's allegations were not included in the agreement reached to authorize an FBI investigation last week. Everyone she has named as being at the "gathering" where the assault allegedly happened has denied that the "gathering" ever took place, and this includes Ford's close friend Leland Ingham Keyser. Kavanaugh has denied the incident.
But he said they are not following up at all on Ramirez's account that Kavanaugh thrust his genitals in her face, forcing her to touch them without her consent, during an alcohol-fueled party when they were students at Yale University in the mid-1980s.
McConnell's job of wrangling key Republican senators - he can afford to lose only one vote from his caucus - may have gotten harder after Trump decided the time was right to mock Ford's dramatic testimony to the Senate Judiciary Committee last week.
