The super PAC supporting Jeb Bush for president has released a new video ad attacking GOP frontrunner Donald Trump.
Titled "Tough Enough," the ad begins with a narrator who says "one candidate tough enough to take on the bully."
The ad then quotes Bush's attack line from Tuesday night's GOP debate that went viral.
"Donald, you're not going to be able to insult your way to the presidency. That's not gonna happen," Bush told Trump on stage.
The narrator says Bush, a former Florida governor, is the "one candidate tough enough to take on ISIS" who will destroy the terrorist group and keep the U.S. safe.
"The United States should not delay in leading a global coalition to take out ISIS with overwhelming force," Bush says, in a clip that follows.
"Tested and proven leadership matters," the narrator says.
CBS News confirmed the ad will air on broadcast stations in Iowa and New Hampshire and nationally on Fox News and it cost more than $3 million.
