Former Florida Gov. Jeb Bush aimed his sights repeatedly at Donald Trump during Tuesdays Republican presidential debate, telling the real estate mogul youre not going to be able to insult your way to the presidency.

Bushs first attack focused on Trumps plan to ban all Muslims from entering the U.S.

Its not a serious proposal, Bush said. It will push the Arab world away when we need them to engage.

Trump is great at one-liners, Bush continued. But he is a chaos candidate."
