- Donald Trump has banned immigration from 7 Muslim-majority nations
- White House says Pakistan was considered for Trump's immigration ban
- Visitors from Pakistan are currently subject to extreme vetting in US
"Those were the seven countries that both, Congress and the Obama Administration, identified as being the seven countries that were most identifiable with dangerous terrorism taking place in their country," Mr Priebus said, in an interview, to CBS News.
"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 travelling in and out of those countries," the White House official added.
Presently, visitors from Afghanistan and Pakistan are subject to extreme vetting in the United States, as per Mr Trump's executive order. United States is home to thousands of Pakistani-Americans and Pakistani permanent residents.
"These are the countries that harbor and train terrorists. These are the countries that we want to know who is coming and going in and out of, to prevent calamities from happening in this country," he said.
Mr Trump's immigration ban has met with widespread criticism from political leaders and human rights activists. Protests against the Trump Administration intensified in many parts of United States. A federal judge blocked part of the ban and ordered authorities to stop deporting refugees and other travelers stuck at US airports.
However, the Administration has shown no signs of backing down and the US Department of Homeland Security has said that it would continue to enforce the order but comply with the court's order.
