Former vice president Joe Biden could be the next president of the United States, but this past week hasn’t been favorable for his possible 2020 campaign.

Last Friday, former Nevada state assembly Lucy Flores published an essay claiming that Biden kissed her on the head and touched her in an inappropriate manner in 2014 when she was running for lieutenant governor.

“I couldn’t move and I couldn’t say anything,” she said in an article for New York Magazine’s The Cut blog. “I wanted nothing more than to get Biden away from me. My name was called and I was never happier to get on stage in front of an audience.” 

Biden is expected to announce whether or not he’ll run for president this month and several Democrats have weighed in on the alleged incident.

“I believe Lucy Flores,” Senator Elizabeth Warren told Business Insider. Warren, who has announced her intentions to run for president, did not suggest Biden hold off on running, saying the decision was “for Joe Biden to decide.”

Vermont Senator Bernie Sanders told CBS’ “Face the Nation” that he “had no reason not to believe” Flores.

Former Housing and Urban Development secretary Julian Castro spoke about the matter to reporters while campaigning in Iowa Sunday March 31.

“I believe Lucy Flores,” he said. “I believe that the vice president put a statement out today and we need to live in a nation where people can hear out the truth.”

The statement that Castro is referring to is one that Biden made Sunday, in which he defended his behavior with women, saying in a statement;

“In my many years on the campaign trail and in public life, I have offered countless handshakes, hugs, expressions of affection, support and comfort. And not once – never – did I believe I acted inappropriately. If it is suggested I did so, I will listen respectfully. But it was never my intention.”

Previously, Biden’s spokesperson, Bill Russo, released a response, saying;

“Neither then, nor in the years since, did (Biden) or the staff with him at the time have an inkling that Ms. Flores had been at any time uncomfortable, nor do they recall what she describes,” the statement said. “But [former] vice president Biden believes that Ms. Flores has every right to share her own recollection and reflections and that it is a change for the better in our society that she has the opportunity to do so.”

Flores appeared on CNN‘s “State of the Union” the morning of March 31 and said that Biden’s statement was “Certainly better” than Russo’s. She also made a statement during the State Address, saying politicians need more accountability in sexual misconduct issues.

If Biden is ever to pursue another presidential campaign, 2020 is likely his last shot, as he’ll be 81 when the 2024 election rolls around.
