The fact that Trump refuses to acknowledge that Russia interfered in the 2016 election tells you everything. We don’t need the Mueller Report to tell us (or not tell us) that Trump is a traitor. His own actions speak for themselves:
The President of the United States, like all elected officials and public servants, swears to uphold and defend the Constitution against all enemies. But there is one responsibility the president must bear alone, and that is the obligation to act as the commander in chief, the guardian of our national security and the defender of our nation from malevolent foreign powers. The Mueller report makes clear that Donald Trump has failed miserably in this sacred obligation, and instead has traded his constitutional duty for his own safety.
