Stephanopoulos, who worked in her husband's White House, asked the former secretary of state a number of questions about the ongoing email scandal, including bringing up a negative report that came out last week from the office of the State Department inspector general.
The inspector general said in the report that Clinton had 'an obligation' to discuss using personal email with State Department officials and a request to use personal email would have been refused 'because of the restrictions in the foreign affairs manual and the security risk in doing so.'
'Do you now accept their conclusion that your exclusive use of a personal account was not allowed, that you broke State Department rules?' Stephanopoulos prodded.
'You know, look, George, I thought that the report actually made it clear that the practice I used was used by other secretaries, other high ranking State Department officials,' Clinton answered.
When the journalist pointed out that no other secretary of state had used persona email exclusively, Clinton cut in, saying that in hindsight she wouldn't have done it over again.
'But I think that the rules were not clarified until after I had left, because it had been the practice of others,' she said.
She noted that what she did was keeping in line with others' practices.
'George, I have to tell you that, you know, I will say it was a mistake, I would not do it again,' she said.
'But I think that the rules were not clarified until after I had left and the first secretary of state to use a government email account was John Kerry some months into his tenure,' she continued.
'Those are the facts,' she added.
Stephanopoulos tried again, noting how the report had called Clinton unmindful of the rules in place.
'Everybody in the department knew I was emailing from a personal address,' Clinton said. 'Hundreds of people knew it.'
'People around the government knew it and, you know, that was what the practice has been and that's what I did as well,' she added.
Then when asked if the FBI had contacted her, she answered that the FBI hadn't asked for an interview yet.
The email scandal has been a perpetual thorn in Clinton's side and still could cause great political damage.
Not only is there the ongoing FBI investigation, but a number of Clinton's top aides are testifying about the former secretary of state's secret server as part of a Freedom of Information Act lawsuit, courtesy of conservative group Judicial Watch.
On top of that, the House Committee on Benghazi – the panel that uncovered Clinton's private email use – has yet to release the findings of its investigation and could do so before the Democratic National Convention or the November election.
