U.S. President Donald Trump has signed ‘extreme vetting’ executive order for people entering United States. He signed the executive order at the pentagon after a ceremony to swear in James Mattis as Defence Secretary.

Hours after the President signed the order, there were still no details from the white house on how it would work. But in a TV interview, he said Christians would be given priority among Syrians who apply for refugee status.

He also signed an Executive Order aimed at rebuilding the military by “Developing a plan for new planes, new ships, new resources and new tools for our men and women in uniform”.
