Today the Supreme Court heard oral argument in Trump v. United States, the presidential immunity case. Much of the argument concerned issues left unresolved during the Trump presidency.
First, during the Mueller investigation, it was alleged that Trump violated the federal obstruction of justice statute. I, and others, countered that a criminal statute should only apply to the President if there is a "clear statement" to that effect. In other words, a general criminal statute should not be read to apply to the President.
Second, it is true that in 1995, the Office of Legal Counsel suggested in an opinion that the federal bribery statute, 18 U.S.C. § 201, would apply to the President, even though there was no "clear statement." But bribery is somewhat unique in that the Constitution expressly enumerates bribery as a ground of impeachment. It is difficult to then argue that the President has some sort of constitutional authority to engage in impeachable conduct.
