Courage and Grace
The twice Speaker of The US House of Representatives is the most powerful and influential woman in politics and POTUS knows it and so does everyone else.
In fact, Trump does not like to share the limelight, so when CBS 60 Minutes just profiled Nancy Pelosi, it made him so jealous that he called it a "puff piece" interview with The Speaker of Congress.
Whenever he does not like something, instead of proposing an alternative, he attacks because he apparently does not know what else to do and can not control himself. Is it because he really lacks courage and grace?
