"When you talk about George Bush, I mean, say what you want, the World Trade Center came down during his time," Trump said in an interview with Bloomberg TV.
"How pathetic for @realdonaldtrump to criticize the president for 9/11. We were attacked & my brother kept us safe." Jeb Bush tweeted.
"No @JebBush, you're pathetic for saying nothing happened during your brother's term when the World Trade Center was attacked and came down," Trump fired back.
