WASHINGTON (Diya TV) — The White House indicated Monday that Pakistan could be added to the list of seven countries included in President Trump’s executive order, which prohibits travelers and refugees from specific Muslim-majority nations from entering the U.S. for 90 days.

“The reason we chose those seven countries was, those were the seven countries that both the Congress and the Obama administration identified as being the seven countries that were most identifiable with dangerous terrorism taking place in their country,” White House Chief of Staff Reince Priebus said.

Signed last Friday, Trump’s controversial executive order brought the U.S. refugee program to a screeching halt for 120 days, indefinitely banned Syrian refugees from entering the country, and prohibits travelers entry from Iran, Iraq, Libya, Sudan, Yemen, Syria and Somalia.

“Now, you can point to other countries that have similar problems, like Pakistan and others. Perhaps we need to take it further. But for now, immediate steps, pulling the Band-Aid off, is to do further vetting for people traveling in and out of those countries,” Priebus said during an interview with CBS News.

The executive order currently says visitors from countries such as Afghanistan and Pakistan are subject to “extreme vetting.”

Priebus said, contrary to public belief, that Trump didn’t just put ink on paper and start signing, there was a lot of work and planning that went into the action.

“We’re not going to advertise to the world that we’re going to put a stop or at least a further vetting on travel in and out of our country from these seven places,” Priebus said.

“Some people have suggested, that, well, maybe we should have given everyone a three-day warning. But that would just mean that a terrorist would just move up their travel plans by three days. Identifying too many people in these countries and giving them a heads-up in these countries would only potentially flag the executive order for bad order,” he said.

“The president has a call with leadership in Saudi Arabia and the United Arab Emirates and other countries around world. And I’m sure this topic may come up,” he said.

Priebus said, first and foremost, the safety and security of all Americans is why the Trump administration took the action.

“These are countries that harbor and train terrorists. These are countries that we want to know who is coming and going in and out of to prevent calamities from happening in this country.

“We’re not willing to be wrong on this subject. President Trump is not willing to take chances on this subject. He was elected president in many respects because people knew that he was going to be tough on immigration from countries that harbor terrorists.

“I can’t imagine too many people out there watching this right now think it’s unreasonable to ask a few more questions from someone traveling in and out of Libya and Yemen before being let loose in the United States. And that’s all this is.”
