Former Vice President Joe Biden Joe BidenOmar fires back at Trump over rally remarks: 'This is my country' Trump mocks Biden appearance, mask use ahead of first debate Trump attacks Omar for criticizing US: 'How did you do where you came from?' MORE, accused of inappropriately touching and kissing a former Nevada lawmaker in 2014, is facing his own #MeToo moment ahead of a likely 2020 run.

After the ex-state official, Democrat Lucy Flores, came forward with the allegations on Friday, a number of Democrats raised concerns about Biden's campaign on the Sunday shows circuit, with many saying they believe her accusation.

Biden, who also faced criticism Sunday from the White House, said in a statement Sunday that he has “offered countless handshakes, hugs, expressions of affection, support and comfort" but doesn’t believe he ever acted inappropriately.

"If it is suggested I did so, I will listen respectfully. But it was never my intention,” he added.

But in the #MeToo era, Biden is likely to face ongoing questions over the alleged incident, which serves as an early test for a campaign that has yet to officially launch.

Flores said in an essay published Friday in New York Magazine's The Cut that Biden touched her shoulders and kissed the back of her head before a Nevada campaign event in 2014.

"As I was taking deep breaths and preparing myself to make my case to the crowd, I felt two hands on my shoulders. I froze. 'Why is the vice-president of the United States touching me?'" she wrote.

"I felt him get closer to me from behind. He leaned further in and inhaled my hair. I was mortified. I thought to myself, 'I didn’t wash my hair today and the vice-president of the United States is smelling it. And also, what in the actual fuck? Why is the vice-president of the United States smelling my hair?' He proceeded to plant a big slow kiss on the back of my head," she added.

Appearing Sunday on CNN’s “State of the Union,” Flores called on Biden to “acknowledge that it was wrong.” She also said she believes the alleged incident is “disqualifying” for a presidential run but added that “it’s up to everybody else to make that decision.”

Other Democrats — including several of Biden’s 2020 rivals — stopped short of calling the accusation disqualifying on Sunday, though they indicated they believe Flores and that Biden needs to face more questions.

“I’m not sure that one incident alone disqualifies anybody. But … this is an issue not just that Democrats or Republicans, the entire country has got to take seriously,” Sanders said.

“I think Joe Biden has a big problem here because he calls it affection and handshakes. His party calls it completely inappropriate," Conway said during an interview on "Fox News Sunday” while also calling Flores “bold” for coming forward.

In her essay Wednesday in New York Magazine, Flores wrote that Biden’s potential bid for the presidency was what prompted her to share her story.

“I would be lying if I said I didn’t carefully consider all of this before deciding to speak,” she wrote. “But hearing Biden’s potential candidacy for president discussed without much talk about his troubling past as it relates to women became too much to keep bottled up any longer.”
