The former United States president said: "I dealt with it 20 years ago, plus".
"This was litigated 20 years ago, two-thirds of the American people sided with me".
"I've never talked to her", he admitted. "The apology was public", said Clinton.
"If the facts were the same today, I wouldn't", said Clinton, who was doing the Today show interview along with author James Patterson to promote a new book they've written together titled "The President Is Missing".
Clinton, 71, was impeached by the House of Representatives in 1998 for perjury and obstruction of justice after admitting to a sex scandal with Lewinsky, but was acquitted by the Senate in 1999.
Indeed, that's the frame CBS News used to corner Clinton into revisiting past scandals, asking him, "Because the fictional president ... is under threat of impeachment, how do you look back at your impeachment?"More news: Upcoming Assassin’s Creed is set in Ancient Greece
McGowan was among the first to accuse disgraced media mogul Harvey Weinstein of raping her and has been an outspoken champion of the #MeToo movement. Melvin pressed Clinton on that point, prompting the former president to issue a fiery defense of his record. "He was 27 years my senior, with enough life experience to know better", she wrote.
He also said that he had never privately apologised to Lewinsky and that he did not feel he needed to.
Lewinsky said in an article published in Vanity Fair in February that she had been reexamining her affair with Clinton through the "new lens" of the #MeToo movement and has concluded it constituted a "gross abuse of power".
Trump, too, has been accused of an array of sexual misconduct by at least 19 different women, ranging from unwanted kissing and groping to sexual assault and harassment. "But you typically have ignored gaping facts in describing this, and I bet you don't even know them", Clinton told Melvin.
"Clinton added that those in the "#MeToo" movement are partly "frustrated" by allegations against President Donald Trump not being acted upon or taken seriously.
At the time of the scandal, Clinton attributed his affair with Lewinsky to sin and repentance after lying under oath.
"I dealt with it 20 years ago, plus", said Clinton. He hadn't apologized to her directly. "We're supposed to be able to say what the difference is between right and wrong, and when you have done something wrong, you are supposed to own it and not talk about facts, distorted facts and obstructed facts". Clinton said he would not have, adding that he did support MeToo and that the movement was long overdue. "All he needed to say in the interview is 'I am profoundly and deeply sorry'".
