Bill Clinton's sexual conduct with former White House intern Monica Lewinsky was "the most appalling behavior by an American president" in U.S. history, Mike Pence charged Sunday — drawing a sharp contrast with sexually aggressive remarks made by Donald Trump.

In an interview on CBS News' "Face The Nation," the Indiana governor and GOP vice presidential nominee said Trump has apologized for a lewd 2005 hot-mic video — and has denied accusations of multiple women who've accused the GOP nominee of groping them.

"Bill Clinton didn't just talk about doing things," Pence said. "He did them."

"It took a while to find all that out," he continued. "He was under oath in 1998 and he finally came clean on having taken advantage of a 23-year-old intern at the White House named Monica Lewinsky in the most appalling behavior by an American president in the history of this country."

Pence called it "really remarkable … in a week where you have this series of unsubstantiated allegations… we have an avalanche of hard evidence about Hillary Clinton's years as secretary of state and the Clinton foundation…"

"It's been largely ignored by this network and the mainstream media and the American people see right through it," he said.

In a separate interview with "Fox News Sunday," Pence said Americans are "very troubled" about the timing of the groping charges against Trump.

"The timing of these unsubstantiated claims that have come forward, all of which Donald Trump has categorically denied, is I think deeply troubling to millions of Americans," he said.

"I know there's countervailing evidence that’s coming out right now, and more information will probably come. But the American people are very, very troubled."
