Hillary Clinton's presidential campaign has unveiled a new ad attacking Donald Trump as too dangerous to be president of the United States.

The ad juxtaposes some of Trump's controversial statements alongside a narrator's description of the characteristics of a proper commander in chief.

"In times of crisis, America depends on steady leadership," a narrator says in the ad before showing clips of Trump saying, "I know more about ISIS than the generals do, believe me" and "You can tell them to go [expletive] themselves."

"Because all it takes is one wrong move," the narrator continues before audio of Trump plays saying "I would bomb the [expletive] out of 'em."

The 30-second ad, titled "Just One," will be folded into the Clinton campaign's existing national cable advertising ad buy.
