I don’t know about that, for sure. I think probably not-as-much might happen to Hillary given the absence of direct evidence.
I just won’t blame the absence of evidence on Gowdy, as many here choose to do.
For starters he could refrain from treating Clinton deferentially. Don’t ask her to testify, COMMAND. Issue a subpoena duces tecum, if she fails to comply she can be held in Contempt of Congress and then arrested and imprisoned.
