Charles Krauthammer told viewers Tuesday on "Special Report with Bret Baier" that he now considers presumptive Democratic presidential nominee Hillary Clinton a "non-criminal liar," after the Federal Bureau of Investigation failed to recommend prosecution following the investigation into Clinton’s emails.

"The lying is obvious when you compare her statements with what Comey said," said Krauthammer, a syndicated columnist and Fox News contributor.

FBI Director James Comey made his recommendation Tuesday in a news conference where he did not take questions from the press.

Comey explained that, although Clinton and her colleagues were "extremely careless" in their handling of classified information, the team of investigators did find any evidence regarding intent that would justify a criminal prosecution.

The Clinton campaign released a statement after Comey's announcement saying they were "pleased" with the FBI's handling of the investigation.

Krauthammer said he found Comey's logic puzzling in his announcement.

"He laid the case for gross negligence. He accused her of extreme carelessness and then he laid out the fact that she should have known, she did know, and then he created a completely irrelevant new standard, which is malicious intent," he said. "But negligence does not require intent."
