Julian Assange, founder of WikiLeaks, said Tuesday night that Hillary Clinton is not telling the truth when she says she didn't know what the classified "c" marker used in government email correspondences during her time at the State Department meant.

"She is lying," Assange told Fox News' Sean Hannity. "And it is disturbing that [FBI Director James] Comey goes along with that game."

Notes of Clinton's testimony to the FBI released Friday show that the former secretary of state said she could not remember what the symbol meant.

"When asked what the parenthetical 'c' meant before a paragraph within the captioned email," read the FBI's notes of an interview with Clinton released Friday . "[Clinton] stated she did not know and could only speculate it was referencing paragraphs marked in alphabetical order."

"Hillary Clinton says that she can't remember what a 'c' in brackets stands for. Everyone in positions of government, and in WikiLeaks, knows it stands for Classified/Confidential," Assange said.

"By Hillary Clinton, here she is. See, that is her signature. With a 'c' in bracket right there," Assange said to Hannity, holding one such email up. "Thousands of examples where she herself has used a 'c' in brackets by herself. And more than 22,000 times where she has received cables from others with this 'c' in brackets. So it is absolutely incredible for her to lie."

FBI Director Comey concluded in July that Clinton's State Department had been "extremely careless in their handling of very sensitive, highly classified information" but that "no reasonable prosecutor" would bring charges against Clinton.
