President Donald Trump reaffirmed his support for Supreme Court nominee Brett Kavanaugh in a tweet late Monday and blamed Democrats for working to destroy a “wonderful man” by casting a series of “false accusations.”

The support comes amid new allegations of decades-old sexual misconduct against the nominee.

“The Democrats are working hard to destroy a wonderful man, and a man who has the potential to be one of our greatest Supreme Court Justices ever, with an array of False Accusations the likes of which have never been seen before,” Trump tweeted.

Christine Blasey Ford has accused Kavanaugh of covering her mouth and trying to remove her clothing at a party in the early 1980s, when they were both in high school. The New Yorker reported allegations from Debbie Ramirez on Sunday, who claimed Kavanaugh exposed himself to her during a party at Yale University when he was a freshman.

Michael Avenatti, the attorney for porn star Stormy Daniels, said he has information that Kavanaugh and high school friend Mark Judge had plied women with drugs and alcohol at parties so other men could gang rape them. Kavanuagh called the allegations "totally false and outrageous."

In an exclusive interview with Fox News’ Martha MacCallum on Monday, Kavanaugh denied the allegations against him and said he wants a “fair process where I can defend my integrity, and I know I'm telling the truth.”

"What I know is the truth, and the truth is I've never sexually assaulted anyone," Kavanaugh said. "I want a fair process where I can defend my integrity, and I know I'm telling the truth. I know my lifelong record, and I'm not going to let false accusations drive me out of this process. I have faith in God and I have faith in the fairness of the American people."

Kavanagh and Ford are set to testify at a hearing on Thursday after days of back-and-forth negotiations between Ford's legal team and Senate Republicans.

Senate Majority Leader Mitch McConnell, who delivered a nationally televised speech on the Senate floor Monday defending Kavanaugh, vowed an up-or-down vote on the nominee after the planned hearing on Thursday.

“This shameful smear campaign has hit a new low," McConnell said, recalling that Democrats had promised to stop a generational rightward shift on the Supreme Court by "any means" available. "Senate Democrats are trying to destroy a man’s personal and professional life."

McConnell also reiterated that none of the allegations against Kavanaugh -- including the claims published Sunday in The New Yorker and last week by The Washington Post -- had any first-hand corroboration.

Republicans on the Judiciary Committee do not expect, however, to be able to vote on Kavanaugh's confirmation until Friday at the absolute earliest. That would almost certainly mean that the Supreme Court would be without a ninth justice when its next term begins Oct. 1, a date set by federal law.
