David Petraeus, former general and CIA director, is speaking out about the presidential election and Hillary Clinton‘s emails in a new interview.

The interview is airing in full on Fox Business Network tomorrow, on the brand-new program Wall Street Week, and in a preview clip that aired earlier today, Petraeus reacted to being asked about the Clinton email controversy and whether she’s been treated differently than he was.

For background, that infamous scandal that caused Petraeus to resign as CIA director involved revelations that Petraeus leaked classified information. He pled guilty, and some Republicans believe that he and Clinton aren’t being treated the same way.
