General Kelly's jobs as Chief of Staff of the Whitehouse is stopping the leaks. The leaks come from clashes in the Whitehouse and like the transcript of Trump's phone calls are super dangerous and must be stopped. The clashes are between 1- the far right nationalists like Bannon and Miller, and 2- the globalist like Generals Mattis, Kelly, and McMaster, and Admiral Rogers, and Global Businessman Tillerson. The nationalists have the upper hand now on immigration policy (although the policy out now is from the Republicans in Congress and not Trump). The other big battle is over Middle East policy where the nationalists want to pull out, and the Generals and the military want to build our forces. Afghanistan where military wants more troops and Trump has said no for now is the big internal fight.  These internal fights lead to the leaks. McMaster who has yet to prove himself to Trump has been rumored to be one of the leakers directly or through his staff-- see what Kelly does.
