While Clinton continued to stress that her use of a private email account and server as the US top diplomat was 'allowed' and 'above board', she showed her greatest contrition yesterday since the issues started earlier this year.

"But in retrospect, as I look at it now, even though it was allowed, I should have used two accounts," said Clinton. "That was a mistake. I'm sorry about that. I take responsibility.”

The remarks came only one day after Clinton refused to apologize for her use of a private email account and server with The Associated Press, saying what she did was allowed.

However, a number of national polls showed that as Clinton fails to end controversy around her exclusive use of her private email account and server from 2009 to 2013, an increasing number of voters start to question her trustworthiness and honesty.

At a press conference in March, Clinton said she had exchanged about 60,000 emails from her private email account during her stint in the Obama administration, among which about half were personal and thus deleted.

The controversy around Clinton's email practices again burst into public view earlier August after the inspector general for the U.S. intelligence community revealed that two of the thousands of emails held by Clinton contained top secret information.
