From day one it seemed to me like Trump's main goal was desecrating the federal state institutions. Seriously, the guy seems as if he cares only about stepping on the constitution and laws. Correct me if I'm wrong, but don't POTUS executive orders only serve to direct the federal government, his employees? Twitter is definitely not a federal agency. Why are a lot of people treating this situation like Trump is able to circumvent the legislative branch?
