Thats an excuse. Even if Trump were to drain the DOJ (many Presidents before him have fired almost all federal prosecutors) the Senate wouldnt do squat. This mantra that boogey man republicans are going to side with democrats to impeach an action constitutionally protected and reserved to the Executive is HOG wash. Its just a way to make an excuse and then continue whining about Congress.
One man against a 4 trillion dollar corrupt stasi state[in firm control by the radical left], both parties, corrupt courts and fakestream media. That makes him a PINO. President in Name Only.
I include your poster boy, count copulot aka ted cruz, amongst the neverTrumpers and rinos(comprising the GOP) who are helping the corrupt state carry out their coup because of their silence. Most of the GOP are openly supporting mueller and his coup.
This is years old news. Where have you been?
