Senator Bernie Sanders apologized Thursday to women who said they were subjected to sexual harassment or misconduct while working for his 2016 presidential campaign. "I intend in every way to be actively involved in that process", Sanders wrote. "The allegations speak to unacceptable behavior that must not be tolerated in any campaign or any workplace".
"To women in our campaign who were harassed or mistreated, I apologise", the Vermont independent wrote in a statement on Twitter on Thursday. "Our standards and safeguards were inadequate".
Robert Becker - who oversaw Sanders' campaign in Iowa and, as deputy national field director, subsequently lead the senator's efforts in California, Michigan and NY - allegedly approached the 20-year-old female staffer later that night and grabbed her wrists before forcibly kissing her, the woman and three additional sources cited by Politico claim.
Becker, 50, has denied the allegations.
"I am very proud of the 2016 presidential campaign we ran, and of the staff and volunteers who made our successes possible", Sanders said in the statement posted to Twitter.
The woman chose to go public when Becker contacted her about a potential place in Sanders' possible 2020 campaign for president.
Allegations of sexual misconduct and an "untenable and unsafe dynamic that developed during [the Sanders] campaign" have dogged the Vermont senator in recent weeks, according to Politico.
Sanders has not personally been the focus of any of the accusations.
The New York Times also reported earlier this month on the allegations of sexism from female staffers that worked on the Senator's 2016 campaign against former Secretary of State Hillary Clinton.
The Vermont senator's campaign committee, Friends of Bernie Sanders, said Becker "would not be a part of any future campaigns".
"I was little bit busy running around the country trying to make the case", Sanders told CNN on January 2.
He thanked the women who did come forward with complaints of sexual misconduct and ensured that his 2018 Senate re-election campaign had "established some of the strongest sexual harassment policies in the country".

Politico's report said the "female staffer did not report the incident immediately because the campaign had just ended at the time of the incident".
"We are addressing what happened on the Bernie campaign but as people that work in this space we see that all campaigns are extremely unsafe to women and marginalized people and we are attempting to fix that", the campaign staffers wrote.
Several other high-profile former and current lawmakers have been embroiled in sexual harassment allegations against their aides.
