Lawrence: Elon Musk says ‘unrepentant racists’ support Trump

A U.S. military veteran killed 14 people in New Orleans in another homegrown terrorist attack. MSNBC’s Lawrence O’Donnell says that when Donald Trump sees the type of terrorist attack that occurred in New Orleans, he doesn’t remember the deadly terrorism suffered at the hands of people like Timothy McVeigh, instead he blames the criminals he imagines are crossing the southern border.
