A news comment was made that John Brennan, former Director of CIA, has passed the statute of limitations for any wrong doing, corruption, collusion, etc with FBI, State Department and Obama Administration. Other persons of the purported "Deep State" may not be so lucky. However, I'm thinking that AG Sessions has shown too much delay and may be enough of the swamp himself to drag out the "investigations" until all persons involved have reached that bench mark.
In my mind, corruption to destroy our government or to overthrow it by criminal means, is treason and should be treated as same. No statute of limitations for capital crimes, and should be none for treason. They should meet the same end.
