Donald Trump can’t stop picking fights with dead people. First came his attacks on Republican war hero John McCain, now he’s offered up some derisive comments about another giant of the party, Barbara Bush. The former first lady delivered some damning comments on Trump before her death almost a year ago. In the new book The Matriarch: Barbara Bush and the Making of a Dynasty, she’s quoted as calling Trump “a symbol of greed” and saying she no longer considered herself to be a Republican because of his presidency. In a Washington Times interview, Trump hit back at those comments. “I have heard that she was nasty to me, but she should be. Look what I did to her sons,” said the president. He went on to lay into her son Jeb Bush, saying: “Look, she’s the mother of somebody that I competed against. Most people thought he [Jeb Bush] was going to win and he was quickly out. I hit him very hard in South Carolina.”
