Vice President Joe Biden said Friday that he wished he could physically confront Republican nominee Donald Trump over lewd comments the real estate mogul made about women that were captured on tape in 2005.

"The press always asks me don’t I wish I were debating him," Biden, 73, said of the 70-year-old Trump. "No, I wish we were in high school—I could take him behind the gym. That’s what I wish."

Biden addressed Trump's comments while appearing at a campaign event for Democratic nominee Hillary Clinton in Wilkes-Barre, Pa.

BIDEN: TRUMP REMARKS ARE 'SEXUAL ASSAULT,' BILL CLINTON'S PAST SHOULD'NT MATTER

"What he says he did and does is the textbook definition of sexual assault," Biden said. "It's more than that. He said because I'm famous, because I'm a star, because I'm a billionaire, I can do things other people can't. What a disgusting assertion for anyone to make."

Trump was recorded bragging about kissing and groping women in a conversation with "Access Hollywood" host Billy Bush, at one point using a vulgar term for a part of a woman's anatomy. The tape was made public earlier this month, two days before the second of three debates between Trump and Clinton.

There was no immediate response from the Trump campaign to Biden's comments.

Earlier Friday, Trump took a shot at first lady Michelle Obama at a campaign event in North Carolina, saying that "all she wants to do is campaign."

Trump then said that Michelle Obama had attacked Clinton during the 2008 presidential race, when she said, "if you can't run your own house, you certainly can't run the White House." The Obamas have repeatedly denied that the remark was a reference to Hillary Clinton remaining with her husband through his extramarital affairs.

"I said, we can't say that, it's too vicious," Trump told his audience. "They said, 'Michelle Obama said it.' I said, 'She did?' but we don't hear about that."

Michelle Obama has emerged as one of the most effective voices for Clinton in the late stages of the campaign and has repeatedly criticized Trump's treatment of women.

Typically self-assured, Trump appeared to be unusually candid about the possibility of losing. He said Friday he is packing his schedule with campaign events through Election Day so he will know he spared no effort and have no regrets.

"I will be happy with myself," Trump said.
