President Trump on Monday declared Justice Brett Kavanaugh innocent of claims of sexual misconduct lodged against him by three women and offered an apology to Kavanaugh and his family for the “terrible pain and suffering” they endured during his nomination process.

“Those who step forward to serve our country deserve a fair and dignified evaluation, not a campaign of political and personal destruction based on lies and deception,” Trump said during a ceremonial swearing-in of Kavanaugh at the White House. “What happened to the Kavanaugh family violates every notion of fairness, decency and due process. In our country, a man or a woman must always be presumed innocent unless and until proven guilty. And with that, I must state that you, sir, under historic scrutiny were proven innocent.”

Kavanaugh, who Trump nominated to replace retiring Justice Anthony Kennedy on the Supreme Court in July, was confirmed 50-48 by the Senate on Saturday after a bitter and political confirmation fight.

Three women accused Kavanaugh of sexual misconduct dating back more than three decades ago. One, Christine Blasey Ford, said Kavanaugh sexually assaulted her during a small gathering at a Maryland house in 1982.

Kavanaugh categorically denied the allegations.

Both he and Ford appeared before the Senate Judiciary Committee in an extraordinary hearing late last month and offered raw and emotional testimony.

The Senate moved forward with its vote on Kavanaugh’s nomination after the FBI completed a supplemental background investigation into Kavanaugh and the allegations against him.

Senate Republicans said the probe offered no corroborating evidence of Ford's claims, while their Democratic counterparts scorned the investigation as having been limited purposefully by the White House.

Kavanaugh took the judicial and constitutional oaths, administered by Chief Justice John Roberts and Kennedy, respectively, Saturday. But he and his family appeared alongside Trump at the White House for the ceremonial swearing-in Monday night.

Kavanaugh praised the eight sitting Supreme Court justices, who were all in attendance, in his remarks, and said he harbored "no bitterness" following his confirmation battle.

"The Supreme Court is an institution of law. It is not a partisan or political institution," he said. "The justices do not sit on opposite sides of an aisle. We do not caucus in separate rooms. The Supreme Court is a team of nine, and I will always be a team player on the team of nine."

Kavanaugh also vowed to serve all Americans, acknowledging the partisan and divisive fight that ensued over his nomination and pledging to be a "a force for stability and unity."

"My goal is to be a great justice, for all Americans, and for all of America," he said. "I will work very hard to achieve that goal. I was not appointed to serve one party or one interest, but one nation."
