Former Florida Gov. Jeb Bush (R) again praised his brother’s actions following the terrorist attacks on Sept. 11, 2001, describing President George W. Bush’s leadership as “awe-inspiring.”

“The case study of leadership is how George responded to 9/11, period, over and out,” Jeb Bush told the audience at a Houston event for donors to Bush’s campaign, according to The Hill. “And the idea that a candidate could think that they could make political hay to create a new … narrative on the reality on how he led is a joke.”

During a conversation with his brother on stage, Jeb Bush applauded George W. Bush’s efforts to unite the country.

“People were united. And people really got it that he had a heart for them,” Bush said, according to The Hill. “At that time, as you know, kids were crying. All around people, children and grandchildren didn’t know what was going on.”

“The whole world was turned upside down, and you had a president who was staid and sure and strong.” he continued.

Since launching his campaign for president, Jeb Bush has fiercely defended his brother, even as other Republican candidates attack his record.
