Just because Mr Scarborough was elected does not mean he understands the actions of Judge Robart nor does he fully understand the constitution.  The Legislature can limit the Supreme Court at any time.  The Purpose of the Supreme Court may have been carved out by Judge Marshall but it isn't what is written in the 
constitution.  Judge Robart stuck his foot into something over which he has no legal standing.  Trump does have a wild mouth and he puts his foot into it all too often.  However, Judge Robart does not know what his job is and Joe Scarborough could use a bit of reading time regarding the Constitution and the limits of the supreme court.
