Refugees and visa-holders from seven mostly Muslim countries have been allowed into the US again since last Friday. That's when President Trump's order banning them was temporarily halted by Federal Judge James Robart in Seattle. America's new Chief Executive is outraged and has personally denounced Robart, labeling him "a so-called judge," for putting the country "in peril." The Administration's appealed, but three states, technology companies, foreign policy veterans and civil right groups say reinstating the ban would create more chaos than ever. As the issue winds through the court process, will Trump have a scapegoat to blame for a future act of terrorism?
