US presidential candidate Hillary Clinton has refused to apologize for using a private email server while serving as secretary of state.
Clinton, however, said she was “sorry” that the issue has caused confusion for Americans.
"At the end of the day I am sorry that this has been confusing to people and has raised a lot of questions, but there are answers to all these questions," the Democratic frontrunner told MSNBC in an interview on Friday.
"You know, I was not thinking a lot when I got in. There was so much work to be done. We had so many problems around the world," said Clinton, who was secretary of state from 2009 to 2013. "I didn't really stop and think, ‘What kind of email system will there be?’"
Clinton has come under fire from her Republican rivals in the 2016 presidential race since it emerged in March that she used a personal email account on an unsecured private server for official business.
The former first lady has denied handling classified information on her private server. However, federal investigators, looking into the latest batch of Clinton’s emails released by the State Department, have determined that at least 150 of them contain classified information.
“I take responsibility, I should have had two accounts, one for personal and one for work-related,” Clinton said on MSNBC.
A federal judge has ordered the State Department to release Clinton’s emails once a month on a graduated schedule.
Clinton’s decision to use a private server potentially put thousands of pages of State Department emails at risk, but it also shielded her correspondence from congressional and Freedom of Information Act requests.
The Washington Post reported on Friday that Clinton privately paid a staffer to maintain the server.
The email scandal has plagued Clinton’s bid for the White House with her favorability ratings dropping to a near all-time low.
A new Gallup poll, released on Friday, indicated that a majority of Americans (51 percent) view the Democratic candidate unfavorably as opposed to 41 percent who view her favorably.
