“The Mueller report, as well as the results of the counterintelligence aspects of the investigation, must be made public so that the American people can make an informed decision when choosing their next president. The House of Representatives will play a critical role in determining whether, and to what extent, that happens. The House has broad powers to compel disclosure of information, including classified information, that is necessary to carry out its legislative and oversight functions. It may not be able to get that information without a fight, and that fight will take time. But members of Congress can make a very strong case that, legally, they should prevail. Whatever the end result, it is a battle that is worth fighting. In light of the possibility that Mueller’s team uncovered significant derogatory information about the president and his inner circle, Congress cannot simply ignore the potential ramifications for American security, even if criminal offenses “cannot be established.” The stakes—for the rule of law and for American security—are simply too high.”
