Under this interpretation, extrajudicial execution of TFG and all his congressional enablers (and problematic SCOTUS justices, and followers) would also be AOK. The law couldn’t touch him. Heck, with enough violence, he could head off any impeachment as well.
I don’t see SCOTUS handing that power to a Democrat.
Although knowing Democrats, they’d do nothing with the power, turn over power to Trump, and be wiped out on January 21st.
