Donald Trump said Wednesday that he may tap Rudy Giuliani to lead a commission on terrorism that also would study his controversial plan to block Muslims from entering the US.

The presumptive GOP presidential nominee said on “Fox & Friends” that he may set up the commission to study his immigration policies.

The mogul said a commission would examine his call for a ban on Muslims from abroad until US security has been assured, his proposal to deport anyone in the country illegally and the question of letting in Syrian refugees.

The commission would be “perhaps headed” by Giuliani, who was mayor when New York City was attacked on 9/11.

“It’s a temporary ban,” Trump said on the show when asked if he’d back off the ban to appease House Speaker Paul Ryan.

Trump also said he wouldn’t budge on building a wall with Mexico when he meets with Ryan on Thursday.

“The wall is the wall. People want the wall,” he said.

Trump floated the idea of a commission while assailing President Obama for not using the term “radical Islamic terrorism” after the attacks in France and California last year.

“We have a president that won’t even use the term ‘radical Islamic terrorism.’ He won’t use the term. He refuses to say the term, even after Paris where 130 people were killed or San Bernardino or any other place … It’s a real problem,” he said.

“So we’ll figure it out, and we will get it going. But we have to be extremely careful,” he added.

The mogul did not say if he’d set up a commission only if he wins the White House or launch it during his Republican presidential campaign.

Giuliani said in December that Syrian refugees should not be allowed in the country — but said a ban on Muslims would be unconstitutional.
