Donald Trump has failed to demonstrate the temperament and understanding of our nation’s challenges needed to live up to that responsibility,” Bush writes. The candidates’ spat can be traced to earlier this month, when Trump [seemed to blame George W. Bush](http://time.com/4077095/jeb-bush-trump-pathetic/ "undefined"), Jeb’s brother, for the terrorist attacks on September 11 that occurred during his presidency. Trump then followed up by saying that he could have [prevented the attacks](http://time.com/4077615/donald-trump-bush-september-11/ "undefined"). Bush, meanwhile, called Trump “pathetic” for those comments and criticized him for treating his campaign [like reality television](http://time.com/4077521/jeb-bush-donald-trump-foreign-policy/ "undefined"). ### See Donald Trump Hanging Out With Unlikely Celebrities  Donald Trump, owner of New York's Trump Tower, holds the bridle of a polo pony while talking to Andy Warhol on Nov. 4, 1983.
