"Get the popcorn, Friday & Saturday will deliver on the MAGA promise. POTUS knows he must clean house (gov't) in order to 'free up' and demonstrate who has authority in order to pass important legislation. This was always the priority.

All will come into focus and for anyone to think POTUS is not in control is kidding themselves. Also, he's 100% insulated with zero risk of impeachment (fact)."
