Over the course of my life, recently departed Senator John McCain has had me both cheering, and screaming, but he was absolutely due the same trappings as any other sitting US Senator who kicks the bucket.
Via Talking Points Memo:
According to people familiar with the situation who spoke to the Wall Street Journal, Trump thought the reporting on McCain's passing, just one day after his family announced he would stop seeking medical treatment for his brain cancer, was "over-the-top and more befitting a president," in WSJ's words.
We all doubt Trump knows what befits a President. Trust us, Donald, people are gonna celebrate when you go.
