The issue of free speech has been raised in an ugly Twitter war between President Trump and former congressman turned MSNBC host Joe Scarborough. Earlier this month, the President had asked on Twitter when authorities would open a “cold case” on Scarborough, asking “Did he get away with murder?”. He was referencing the presumed accidental death of a Scarborough staffer with a heart condition who had fallen and hit her head on a desk over two decades ago. The dead woman's widower asked Twitter to delete the President's references to his wife. Today the CEO of Twitter refused. Was this the right decision?
