“but he says Donald Trump’s threat to possibly jail her “is something that we don’t do here.”
Yes we do. A guy who made a film was put in jail because it was convenient to blame his film for the death of US Ambassador Stevens - along with the deaths of patriotic US citizens who tried to protect him. Scooter Libby was put in jail for much less than Hillary has done.
Libby and Martha Stewart are good examples. Prosecuted for lying to investigators. Each could have refused to cooperate, and then they would not be lying. Hillary said she thought "(C)" was alphabetical order. That's a material lie in this investigation.
She also should be prosecuted for mishandling, not just lying.
