Charges of sexual harassment and pay inequity for female staffers during his 2016 presidential campaign are still dogging Bernie Sanders, a new report said Wednesday.

Giulianna Di Lauro, an outreach strategist for Sanders’ operation, complained to her supervisor that she had been harassed by a campaign surrogate when she drove him to events ahead of the Democratic primary in Nevada, The New York Times reported.

She told the paper that the man told her she had “beautiful curly hair” and asked if he could touch it.

She said OK, believing he would just touch a strand of it — but instead, he stroked her hair in a sexual way and kept grabbing and touching her, she said.

She reported the incident to Bill Velazquez, a manager on the Latino outreach team, she said.

But he told her: “I bet you would have liked it if he were younger,” according to her account and a woman who witnessed the exchange.

Other accounts of sexual harassment in Sanders’s 2016 campaign have circulated recently on social media, The Times reported.

The allegations raise issues about the Vermont senator’s viability as a candidate for 2020 in the wake of the #MeToo movement and heightened awareness of harassment and sexual misconduct.

Sanders’ campaign responded with a statement that said it “will not tolerate harassment,” while admitting there were issues in the past.

“During 2016 there were a number of HR actions taken, and while it is not appropriate to discuss them individually, actions taken ranged from employee counseling to immediate termination from the campaign,” read a statement released on Wednesday.

Jeff Weaver, Sanders’s 2016 campaign manager and now a top adviser, said in an email to the paper that “anybody who committed harassment on the campaign would not be asked back” and said he regretted some of the campaign’s shortcomings.

Sanders went on CNN later Wednesday and said “I certainly apologize to any woman who felt that she was not treated appropriately, and, of course, if I run we will do better next time.”

When asked by host Anderson Cooper to clarify that he didn’t know of the claims in 2016, he said “Yes, I was a little bit busy running around the country trying to make the case.”
