Congress needs to step up and keep filing articles of impeachment. Get the republicans on record defending every criminal act, and then beat them in the midterms.
Impeachment? Midterms? Those words are meaningless now. The system has been broken and dismantled. You can't vote your way out of fascism. The fight needs to be fought on every front, including those ones, but they will not save you.
The only way out is for the population to rise up in mass protest.
