Clear the air once and for all

According to the draft copy of Trump's executive order, the countries whose citizens are barred entirely from entering the United States is based on a bill that Obama signed into law in December 2015. http://iranprimer.usip.org/blog/2015...isa-waiver-law

Obama signed the Visa Waiver Program Improvement and Terrorist Travel Prevention Act as part of an omnibus spending bill. The legislation restricted access to the Visa Waiver Program, which allows citizens from 38 countries who are visiting the United States for less than 90 days to enter without a visa.

In February 2016, the Obama administration added Libya, Somali and Yemen to the list of countries one could not have visited — but allowed dual citizens of those countries who had not traveled there access to the Visa Waiver Program. Dual citizens of Syria, Sudan, Iraq and Iran are still ineligible, however.

So, in a nutshell, Obama restricted visa waivers for those seven Muslim-majority countries — Iran, Iraq, Syria, Sudan, Somalia, Libya and Yemen — and now, Trump is looking to bar immigration and visitors from the same list of countries.
