Hillary Clinton dodged Wednesday evening when she was asked to comment on a report claiming she told investigators that Colin Powell advised her to use a private email server when she worked at the State Department, an allegation Powell reportedly denies.

The moment occurred during a phone interview with CNN's Anderson Cooper.

"You told FBI investigators that former Secretary of State Colin Powell advised you to use a personal email account," the CNN anchor said.

Powell responded to Clinton's supposed claim this weekend by reportedly saying, "Her people are trying to pin it on me. She was using [a private email server] for a year before I sent her a memo telling her what I did."

Clinton declined to answer Cooper's question.

"I'm not going to re-litigate in public my private conversations with him," she said.

She added, "I've been asked many, many questions in the past year about emails, and what I've learned is that when I try to explain what happened it can sound like I'm trying to excuse what I did and there are no excuses."

The Democratic nominee also stressed she has regrets using a private and unauthorized email serve when she worked at the State Department.

"I want people to know that the decision to have a single email account was mine," she said.

"I take responsibility for it. I've apologized for it. I would certainly do differently if I could but obviously I'm grateful the Justice Department concluded there was no basis to pursue this matter further and I believe the public will be, and is, considering my full record and experience as they consider their choice for president," Clinton said.
