Donald Trump and Jeb Bush were at it again.
Trump upped the ante in criticizing Jeb Bush by slamming his brother George W.'s presidency and at least partially blaming the elder Bush brother for Sept. 11.
"When you talk about George Bush, I mean, say what you want, the World Trade Center came down during his time," he told Bloomberg. When the questioner said he couldn't blame Bush for terrorist attacks, Trump responded this way: "He was president, OK? ... Blame him, or don't blame him, but he was president. The World Trade Center came down during his reign."
