Doing a slow release of "information" without supporting context or details slowly feeds red meat to his base and allows right wing talking heads to go into damage control mode to protect the President. Any review of sensitive information will come with a report on what found and what conclusion if any it makes. This has been a coordinated attempt by the Right to destroy the reputation of the people investigating him to call into question the outcome of the Mueller investigation. As seen in the primaries and the election of 2016 Trump when attacked will return fired and flood the NEWS with what ever he thinks will make his opponent look bad regardless if it's true or not. Remember this is the same man that had the most lies in an election by a landslide.
