While this story may end up as nothing more than a witch hunt, it exposes serious problems with Trump's administration and glaring faults in his character.  

He threatens, disparrages people who disagree with him, says whatever he thinks people want to hear without regard to truth, speaks out on issues without knowing the facts, etc. 
He is narciscistic and incredibly shallow. He comes across as a child with a temper tantrum when he does not get his way.

He does not have the temperment for public office and should never have been elected much less allowed to stand for election. He may not be impeached but he may get so frustrated by opposition to his policies that he quits anyway. 

In the end the American people will come to accept the mistake they made voting him in.
