By the time she gets around to appearing before Trey Gowdy about the only thing she will be able to say is “I am asserting my 5th amendment rights”
By the time she gets around to testifying before Trey Gowdy, she will do it from her grave. The neutered Pubbies in Congress will roll over to have their bellies scratched.
She will take the same successful tactic Lois Lerner used, make a lengthy “proclamation” of innocence, and then refusing to answer questions about her statement or anything else.
This is Hillary Clinton we're talking about. Rules don't apply to her. I think she just won't appear at all. What are they going to do, arrest her?
