Give me the short list of Democrats that have been investigated by the feds and wound up going to jail for an unrelated lie.
I'll wait.
He will never answer me.
Cite an example, and I'll see what I can find. Because I'm not certain I know of even a Republican example that applies to the above.
Scooter Libby.
Uhhh... the investigation for which Scooter Libby went to jail, was about the disclosure of the identities of CIA agents. Scooter Libby went to jail for disclosing the identities of CIA agents... specifically Valerie Wilson. Unless you are speaking about something else, this does not appear to satisfy your premise of being investigated by the Feds, and going to jail for an unrelated lie.
I PM'd this to you at 7:30, I am guessing you didn't see it.
Libby did not out Plame.

This is the same thing that Mueller is doing to Trump associates.
The Feds have the ability to bankrupt you if you do not cop a plea.
