Story highlights Donald Trump is elaborating on his proposed ban of Muslims to the US

The GOP presidential nominee says he's focused country of origin, not religion

(CNN) Donald Trump said his latest proposal to stop immigration "from any nation that has been compromised by terrorism" is an "expansion" of his blanket ban on Muslims, in an interview aired Sunday.

"I actually don't think it's a rollback. In fact, you could say it's an expansion," Trump told NBC's Chuck Todd on "Meet the Press." "I'm looking now at territory. People were so upset when I used the word Muslim. Oh, you can't use the word Muslim. Remember this. And I'm OK with that, because I'm talking territory instead of Muslim."

Trump has not defined which countries would be included in that list of territories.

But in the interview aired Sunday, Trump refused to rule out banning individuals from top US allies like France and Germany, agreeing that "they have totally been" compromised by terrorism.

Trump's campaign and top surrogates have insisted over the last month that the real estate mogul had backed off his December proposal to bar all foreign Muslims from the US.
