Democratic front-runner Hillary Clinton struggled Wednesday night to answer a question about why she took more than $600,000 in speaking fees from Goldman Sachs in one year.

“Well, I don’t know. That’s what they offered,” she said when asked about the fees by CNN host Anderson Cooper in a forum televised by the network with less than a week away from the Granite State’s first-in-the-nation primary. Clinton had a lucrative turn on the paid speaking circuit after she stepped down as secretary of state, which rival Bernie Sanders has used as fodder against her.

“I wasn’t committed to running. I didn’t know whether I would or not,” she added when asked why she took the money knowing it would look bad if she ran. She said she did not regret taking the money, noting that other former secretaries of states have given paid speeches and saying that no one can influence her.
