"Just say that the election was corrupt, and leave the rest to me and the Republican congressmen." -- malignant coup plotter Donald Trump, December 27, 2020, as reported by Katie Benner of the New York Times ($$). (See HuffPo's account) That's Trump trying (but failing) to establish a "legal" predicate for the events that were to take place on January 6, 2021.
Doubtless the January 6 select committee will subpoena the Trump Justice officials and the Trump congressional co- conspirators involved, and then let the chips (or criminal referrals) fall as they may.
