Washington - Hillary Clinton says she was "pleased" to speak with the FBI about her use of personal email while serving as secretary of state, but refused to discuss reports that she will not face charges.
In an interview aired Sunday, Clinton acknowledged it was unwise for her husband to meet with America's top law enforcement officer, with the encounter coming in the midst of the FBI investigation that has dogged her campaign to become the first female president of the United States.
"Hindsight is 20/20," Clinton told NBC's Meet the Press programme, noting that both Bill Clinton and Attorney General Loretta Lynch have said they would not do it again.
The pair held an impromptu meeting at the airport in Phoenix, Arizona last week.
Clinton, who was interviewed by the FBI on Saturday for about 3.5 hours, refused to speculate on the timeline or possible conclusions of the FBI investigation, and would not comment about reports saying she would not be charged.
"I was eager to do it and I was pleased to have the opportunity to assist the department in bringing its review to a conclusion," Clinton said.
She has apologised for exclusively using a private email account and her own server during her time as secretary of state from 2009 to 2013.
Opponents argue that this breached rules about protecting classified documents from cyber attack and may have amounted to a crime.
The latest NBC News/WSJ poll shows Republican presumptive nominee Donald Trump with a strong lead over Clinton - 41% to 25% - on honesty and trustworthiness.
"I'm going to continue to put forth my record, what I have stood for, do everything I can to earn the trust of the voters of our country. I know that's something that I'm going to keep working on, and I think that's, you know, a clear priority for me," she said.
"When you've been in the eye of the tornado for as long as I have, I know there's a lot of incoming fire, I accept that."
