Hillary Clinton has come out swinging against fellow Democrat Bernie Sanders in a new documentary.
The former presidential candidate accused Sanders - who is among those jostling for the Democratic presidential candidacy - of being an unliked and unproductive "career politician".
"He was in Congress for years," Clinton says in the documentary. "He had one senator support him. Nobody likes him, nobody wants to work with him, he got nothing done.
"He was a career politician. It's all just baloney and I feel so bad that people got sucked into it."
The four-part series Hillary is set to premiere at Sundance Film Festival and will screen on Hulu in the United States in March. The comments made in the documentary were made in 2016.
Sanders has responded to the comments by saying his focus is on Donald Trump's impeachment trial, CNN reports.
"Together, we are going to go forward and defeat the most dangerous president in American history," Sanders said.
In an interview published in The Hollywood Reporter on Tuesday, Clinton said she stood by her comments from the documentary, while also taking aim at those around Sanders.
"It's not only him, it's the culture around him," she told The Hollywood Reporter. "It's his leadership team. It's his prominent supporters. It's his online Bernie Bros and their relentless attacks on lots of his competitors, particularly the women."
Sanders sparked controversy recently after Elizabeth Warren, who is also running for the Democratic candidacy, said the 78-year-old told her in private in 2018 that a woman couldn't win the White House in 2020.
Sanders has denied making the comment, saying it's "incomprehensible" he would think such a thing.
When asked by The Hollywood Reporter whether she would endorse Sanders' nomination, Clinton would not say.
"I'm not going to go there yet," she said.
She did, however, say that the controversy over whether Sanders did or did not make the comment regarding women to Warren was "part of a pattern".
"If it were a one-off, you might say, 'OK, fine.' But he said I was unqualified. I had a lot more experience than he did, and got a lot more done than he had, but that was his attack on me. I just think people need to pay attention because we want, hopefully, to elect a president who's going to try to bring us together, and not either turn a blind eye, or actually reward the kind of insulting, attacking, demeaning, degrading behaviour that we've seen from this current administration."
Clinton said although many people had urged her to consider running for president again, she thought it was the right thing to do to step back.
