Hillary Clinton has defended her progressive record after Democratic rival Bernie Sanders mounted an attack on her links to Wall Street.
“I’m a progressive who gets results and I will be a progressive president who gets results,” she said.
The two Democratic contenders took questions from an audience in New Hampshire, which will pick its presidential nominees in a few days.
Iowa kicked off the state-by-state election earlier this week.
The former secretary of state, Mrs Clinton, was declared the winner in Iowa by a whisker after a prolonged count.
Mr Sanders, a Vermont senator with a big lead in New Hampshire polls, listed issues upon which he thinks Mrs Clinton was not liberal enough – trade agreements, Wall Street regulation, climate change and her backing for the war in Iraq.
“I do not know any progressive who has a super PAC and takes $15m from Wall Street,” said Mr Sanders.
Mrs Clinton, who followed him on to the stage in Manchester, said she was not bothered by his accusation but it was not helpful because they shared the same aspirations.
Under the senator’s definition, President Barack Obama would not be a progressive, she said.
The former first lady was also on the defensive for her speaking fees paid by big businesses, which amount to $9m, according to the Associated Press news agency.
When asked by CNN’s Anderson Cooper why she was paid $675,000 for one event, she said: “I don’t know. That is what they offered.”

Earlier on Wednesday, in response to the same accusation about not being a progressive, she listed her accomplishments in helping minorities and the disadvantaged.
She mentioned her efforts in expanding access to children’s health insurance and her push to support women’s rights and gay rights.
The tensions between the two come as they prepare to debate each other on stage together on Thursday night, five days before the New Hampshire primary vote.
