That statement was about an unclassified account. Now she is saying she did have a classified account. Trying to pin down a Clinton on a fact requires asking a specific question and then independently investigating to find a lie. I would not be surprised if she never had a classified account.
And that's a lie because the State Dept. has been forced to answer whether she ever signed up for a .gov account and they have said there is no record that she ever did.
