There already is precedent.
Nixon's Attorney General John Mitchell was "found guilty of conspiracy, obstruction of justice, and perjury and sentenced to two and a half to eight years in prison for his role in the Watergate break-in and cover-up... The sentence was later reduced to one year from four years... Mitchell served only 19 months of his sentence."
Democrats put a Republican Attorney General in prison, and now our Republican Attorney General is afraid to investigate Democrats for conspiring to spy on political opponents during an election.

Yes, I forgot. But that was a Republican so you can send them to jail.
