Presumptive Democratic nominee Hillary Clinton said Wednesday that she couldn't remember signing a non-disclosure agreement as secretary of state that laid out criminal penalties for mishandling classified information.

In an interview with Fox News host Bret Baier the day after she declared victory in the Democratic primary race, Clinton insisted yet again she never sent nor received any material over her private, unsecured email server that was marked classified.

"Secretary Clinton, you said you sent or received nothing that was marked classified, but you did sign a non-disclosure agreement, an NDA, in 2009 that said markings don't matter, whether it's marked or unmarked. You remember signing that?" Baier asked.

"No, I do not, but the fact is nothing that I sent or received was marked classified and nothing has been demonstrated to contradict that," Clinton said. "What you are seeing acted out is the desire of different parts of the government to retroactively classify material so that it is not made public, since I did ask that all my emails be made public, and this is not an uncommon process."
