Republican presidential hopeful Donald Trump is giving some of the most divisive proposals of his campaign a starring role in his first major television ad, as the unsettled race for the party's nomination swirls around security concerns.

The billionaire businessman is spotlighting his plan to ban Muslims from entering the United States - temporarily and with exceptions, he says - and to build a wall along the southern border.


Trump's campaign says he plans to spend $2 million a week on the ad, set to begin airing Tuesday.

Trump's proposal on Muslims has been condemned by Republicans and Democrats as un-American and counterproductive, yet the hardline approach to immigration has fueled his popularity among the overwhelmingly white Republican primary electorate.

The new ad features dark images of the alleged San Bernardino shooters and body bags.

"The politicians can pretend it's something else. But Donald Trump calls it radical Islamic terrorism. That's why he's calling for a temporary shutdown of Muslims entering the United States until we can figure out what's going on," a narrator says.

Video footage later in the ad shows people apparently streaming freely across a border as the narrator says Trumpwill "stop illegal immigrants by building a wall on our southern border that Mexico will pay for."

Facing questions from news outlets, the Trump campaign acknowledged in a statement Monday that the border images were of a Spanish enclave in Morocco, not the US-Mexican border.

"I think it's irrelevant," Trump said in an interview on Fox News Channel's "The O'Reilly Factor" Monday night. "So you can just take it any way you want, but it's really merely a display of what a dumping ground is going to look like. And that's what our country's becoming very rapidly."

His campaign elaborated in a statement, saying the selection of footage was intended "to demonstrate the severe impact of an open border and the very real threat Americans face if we do not immediately build a wall and stop illegal immigration."

The ad, posted on Trump's website Monday, is a departure from the typical introductory campaign spot, which often features a candidate introducing himself voters or sharing her life story.

But Trump already is well-known to voters. He was the star of the popular "The Apprentice," his name is plastered on high-rise and hotel buildings across the country and he has dominated news coverage over the last six months.

An ABC News/Washington Post poll conducted in December found that 6 in 10 Americans think a ban on Muslims entering the United States is the wrong thing to do. Among only Republicans, however, 6 in 10 say they would support such a policy.

The ad represents the billionaire businessman's first foray into television advertising after spending much of 2015 dominating polls without spending significant resources - at least compared to his rivals.
