Republican presidential candidate Donald Trump on Monday released his first campaign ad — a 30-second video focusing on his plan to ban Muslims from entering the United States.

The ad, titled "Great Again," features Trump vowing to "quickly cut the head off ISIS and take their oil," and explains his decision to close the borders to Muslims.

“The politicians can pretend it’s something else but Donald Trump calls it radical Islamic terrorism,” the narrator says to images of the San Bernardino shooters and masked jihadis. “That’s why he is calling for a temporary shut down on Muslims entering the United States until we can figure out what’s going on.”

The ad also promises to build a wall along the nation's southern border "that Mexico will pay for" in an effort to control illegal immigration.
