President Donald Trump defended his controversial executive order that bars the citizens of Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen from entering the United States, as thousands of protesters chanted outside of the White House and at multiple, major U.S. airports on Sunday in opposition of the president's sudden immigration policy change. Trump denied the ban was religiously-driven, but confused matters by also announcing Christian refugees would get first priority for U.S. entry. Many people now are seeking answers about why Pakistan and Saudi Arabia are not on Trump's immigration ban, which are countries in which Trump companies do business.
