If there is a real question of whether a law was broken, then the person who broke the law should undergo a trial to determine guilt or innocence. Impeachment is the way the President can be put on trial.\n\nWas the information declassified? Was the declassification proper? Assuming both of the above, did the president (or other executive officer) have the legal authority to declassify the information in the manner it was?\n\nI don't know. But if there is a legitimate question of whether one or more laws were broken, the the trial (impeachment) is appropriate. Otherwise, we're basically saying the people in power can break the laws with impunity, and we're back to a monarchy.
