Their comments followed similar ones from Julian Castro, a former US housing secretary, on Saturday night. "It's more clear than ever that Brett Kavanaugh lied under oath," he tweeted. "He should be impeached and Congress should review the failure of the Department of Justice to properly investigate the matter."
Sen. Bernie Sanders of Vermont didn't refer to impeachment by name in a tweet Sunday, but said he would "support any appropriate constitutional mechanism" to hold Kavanaugh "accountable."
Later Sunday, Sen. Cory Booker tweeted: "This new allegation and additional corroborating evidence adds to a long list of reasons Brett Kavanaugh should not be a Supreme Court justice. I stand with survivors and countless other Americans in calling for impeachment proceedings to begin."
Democrats control the House, which holds the power of impeachment. If the House took that route, a trial would take place in the Senate, where Republicans now have a majority, making it unlikely that Kavanaugh would be removed from office.
Trump, who fiercely defended Kavanaugh during his contentious confirmation process, dismissed the latest allegation as "lies."
In a tweet Sunday, Trump said Kavanaugh "should start suing people for libel, or the Justice Department should come to his rescue." It wasn't immediately clear how the Justice Department could come to the justice's defense.
Trump added that they were "False Accusations without recrimination," and claimed his accusers were seeking to influence Kavanaugh's opinions on the bench.
