Weekly Standard columnist Steve Hayes told viewers Monday on "Special Report with Bret Baier" that the latest batch of former Secretary of State Hillary Clinton's emails - set to be released Monday by the State Department - will only put the candidate deeper into hot water.

"It's definitely having an effect," the Fox News contributor said of the email scandal.  "If you listen carefully to the defense we're hearing from Hillary Clinton supporters - it's really no defense at all."

The State Department said Monday that 150 of the emails set to be released are being censored or redacted because they contain information that has since been deemed classified - an issue that Hayes says will become "a huge problem" for Clinton.

"They're saying now, this stuff is still so sensitive that we can't make it public now," Hayes said.  "Well, surely it was more sensitive when she was serving as Secretary of State, and when the information was presumably much more contemporaneous. That's a huge problem for her, there is no good explanation for it, and I continue to think that's why we're not hearing an explanation from her."
