The possibility that Special Counsel Jack Smith ignored a key part of the Supreme Court’s landmark immunity ruling could set the prosecutor up for more heartbreak before the Nine. 

President Trump’s response to Mr. Smith’s 165-page immunity brief is due on Thursday. The special counsel asserts that Trump “must stand trial for his private crimes as would any other citizen.” The 45th president will aim to convince Judge Tanya Chutkan that the case is precluded by the justices’ ruling that official presidential acts are presumptively immune. Trump’s team calls Mr. Smith’s work a “false hit job” and a “monstrosity” that is “politically motivated.”
