He can’t get rid of congressmen. Unless a crime is proven. But I agree.
True, but Trump has a Trump card: DACA. I seen a lot of wailing an gnashing of teeth from some folks here about why he hasn't done anything about that yet. He's holding 750,000 + illegals hostage to make sure his legislative agenda and his SCOTUS pick get through.
And if Congress decides to screw him then he'll veto the Sh*t out of whatever comes across his desk. He'll go scorched earth and make these people beg for mercy, especially when he threatens to pull forces out of Europe.
Congress is the most protected class next to the judicial branch. Congress gets intel updates just like the president. It will be a long 'hunt' to ferret out the criminals, but IF anyone can get it done, Trump can.
