Donald Trump's new TV ad brings up border security.
"And he'll stop illegal immigration by building a wall on our southern border that Mexico will pay for," the ad said.
One problem: That's not the southern border. That's Morocco.
PolitiFact rated this "Pants on Fire."
But Trump's campaign says it wasn't an accident.
"TRUMP CAMPAIGN MNGR: 'No shit its not the Mexican border but thats what our country is going to look like if we don't do anything,'" NBC's Katy Tur tweeted.
