What facts he shared that he's not allowed to share?
He shared what city the intelligence source was in. From this, the Russians can infer which of our allies gave us that intel, and then they can disrupt that source when they are working at cross purposes to the US.
This could cause our ally to no longer share intel about ISIS with us, thus putting American lives in greater danger.
Got it now?
The fat **** is unfit for the office. It's almost as if he is a puppet of the Russians, especially since he had just fired the guy who was investigating whether or not he or his cronies had colluded with the Russians when they interfered in our election.
