Mueller report clears him of collusion. Its plainly worded. Without collusion there is no obstruction. What is in the Muller report is the Obama administration having knowledge of Russian interference in 2014, lied about it, and did nothing about it.
Trump may be the prime example of one's own worst enemy...he acted guilty, he attempted to stop people from completing the investigation because he believed it would be detrimental to him, but, as it turned out, (and what does Trump know that we don't?) he was not found to have lead a campaign actively coordinating with the Russians but he still interfered with the investigation. That is what narcissism, and the fragile ego this maintains, does to a person. It makes you pick fights not because you are vulnerable, but because you perceive beyond reason, that you are vulnerable.
If anything is a joke it is the president and those who see in him any model of confidence or virtue.
And if a foreign government had/has anything on our president, what might we expect his behavior to be then?
