As I write this, the Supreme Court is hearing a case challenging the tradition that nearly all children born in the United States, whoever their parents may be and how they came to be here, are automatically citizens.

On the first day of his second term, President Trump signed an executive order stating that babies born on U.S. soil to illegal immigrants and temporary foreign visitors were ineligible for birthright citizenship. That was an obvious shot across the bow of the U.S. Supreme Court as it challenged an interpretation of the 14th Amendment that has stood for over a century. The President knew his EO would be also challenged, and would eventually end up on the Supreme Court docket.

Because this is an important question that would, if SCOTUS agreed with the President’s interpretation of the Constitutional intent (there were no such things as “illegal immigrants” when the Constitution was written) have massive consequences in many areas, the oral argument is attracting blow-by-blow analysis. That is not my purpose here.

The issue for Ethics Alarms is President Trump’s decision to attend the oral argument. No previous President has done this, although nothing prevents the President from attending. Trump’s predecessors all avoided the option, though there have been many, many cases over the years that the President knew would have a major effect on his policies as well and the matters he had to deal with. President Pierce did not attend the Dred Scott oral arguments. To be fair, he was barely engaged at any time in his miserable four years in the White House. But FDR didn’t sit in while the Court was determining the fates of his many New Deal programs. Nixon didn’t listen to the Pentagon Papers arguments.
