Donald Trump has challenged Chief Justice John Roberts and the Supreme Court, just as he has challenged every other institution of government, but Chief Justice John Roberts seems well prepared to deal with Trump, if and when he gets out of hand.
It is certainly a dangerous struggle, as Donald Trump has an authoritarian bent unlike any earlier President, but it seems clear that Roberts is ready to do what must be done to keep the President within the Constitution.
Earlier in history, there were major confrontations of Thomas Jefferson and Andrew Jackson with Chief Justice John Marshall; Abraham Lincoln with Chief Justice Roger Taney; Franklin D. Roosevelt with Chief Justice Charles Evans Hughes; Dwight D. Eisenhower and Richard Nixon with Chief Justice Earl Warren; Richard Nixon with Chief Justice Warren Burger; and Barack Obama with Chief Justice John Roberts.
But Trump has demanded that the court system favor him in all of his executive orders, and other executive actions, but the Court has refused to back him on a regular basis, leading Trump to say that there are Clinton Judges, Obama Judges, and Bush Judges, but Roberts responding that there are no such descriptions, as all are dedicated to the rule of law, a true rebuke of the President.
On a recent executive order to deny asylum automatically to those who seek it, the Court ruled 5-4 against it, with Roberts joining the four Democratic appointments on the Court, and he has earlier upheld ObamaCare in 2012, and at other times, has sided against conservatives.
It is clear that Roberts sees the Supreme Court as “his Court”, and is concerned about the reputation of the Court long term, so one can be assured that if a case comes up against Trump trying to grab too much power, that he will, likely vote against him, as the entire Court, including three Nixon appointees, voted against him in US V. Nixon of 1974, and when the Court, including two Clinton appointees unanimously voted against Clinton in the Clinton V. Jones Case of 1997.
