US Democratic presidential candidate Hillary Clinton has expressed regret about using a private email server but insisted she never compromised national security.
During a televised national security forum in New York City on Wednesday, Clinton explained how she handled classified materials during her four years as secretary of state between 2009 and 2013.
“There is no evidence my account was hacked,” she said.
Clinton has come under fire for using a private email account and server at her New York home for official emails when she was America's top diplomat.
The email scandal has raised questions about whether Clinton can be trusted to serve as president.
Clinton’s critics, including her Republican rival Donald Trump, have criticized her for endangering government secrets and evading transparency laws.
During Wednesday’s forum, Clinton also said she regretted her decision as a US senator to vote in favor of the 2003 invasion of Iraq.
She said she would not allow the US to be mired in another war in the Middle East if elected president. “We are not putting ground troops into Iraq ever again, and we’re not putting ground troops into Syria,” she said.
A new CNN/ORC Poll shows US Republican presidential nominee Donald Trump has closed the gap with Clinton and leads her nationally in the race for the White House by two points.
Like previous surveys, the new poll also shows that both candidates remain mostly unliked, with majorities saying they have an unfavorable view of each candidate.
Polls taken in the past several months have shown that Clinton and Trump were ranked among the most unpopular presidential candidates in America’s history.
