Regarding the Feb. 11 front-page article “Trump calls for ‘due process’ in abuse cases”:

President Trump has discovered the Constitution and the existence of due-process rights. Perhaps someone can explain to him that due-process rights already were exercised by the parties in one of these cases. Former White House staff secretary Rob Porter’s second wife went through a due-process proceeding in court, invoking both her own and her husband’s due-process rights. As a result of that due process, she was awarded a restraining order against him, to which she was deemed entitled, pursuant to her due-process rights. The White House was informed of this months ago by the FBI.
