Eleven months after Donald Trump called for a ban on Muslims entering the United States, he is warning of terrorism anew with divisive&nbsp;rhetoric similar to what&nbsp;he championed after the Paris and San Bernardino attacks.At an airport rally Sunday in Minneapolis, Trump said Minnesota had&nbsp;suffered a "disaster" as tens of thousands of Somali immigrants, some of them war refugees, had&nbsp;settled in the state over the last few decades."To be a rich nation, we must also be a safe nation, and you know what's going on there," he told the crowd. "Oh, Minnesota. Oh, Minnesota. You know what's going on. You know what I'm talking about. Do you know what I'm talking about? Oh, be politically correct. Just nod. Quietly nod. The whole world knows what's happening in Minnesota."Trump then criticized Hillary Clinton for supporting the admission of Syrian refugees to the United States, drawing a roar of boos for his Democratic rival."She wants virtually unlimited immigration and refugee admissions from the most dangerous regions of the world to come into our country, and to come into Minnesota, and you know better than anybody," he said."Her plan will import generations of terrorism, extremism and radicalism into your schools and throughout your communities. You already have it. When I'm elected president, we will suspend the Syrian refugee program and we will keep radical Islamic terrorists the hell out of our country."It was one of Trump's biggest applause lines in the final weekend of his campaign at rallies in North Carolina, Michigan and other states, and it drew thunderous chants of "USA, USA."Trump said Minnesota had seen first-hand the problems caused by "faulty refugee vetting, with large numbers of Somali refugees coming into your state without your knowledge, without your support or approval."Syrian refugees are subjected to more intense vetting than other immigrants, with multiple federal agencies investigating their background before they are admitted to the U.S. Church groups have helped many of them integrate into American society.Offering no evidence, Trump said some Somali refugees in Minnesota had joined the Islamic State terrorist group and spread "their extremist views all over our country and all over the world.""Honestly, it's hard to believe," he said. "Everybody's reading about the disaster taking place in Minnesota.... You don't even have the right to talk about it. You don't even know who's coming in. You have no idea. You'll find out."Trump mentioned the September stabbing of 10 people at a mall in St. Cloud, Minn., by a suspect who is the son of Somali refugees. He said his administration would not allow refugees to settle anywhere without the community's approval.Trump has never renounced his proposed Muslim ban, which is still posted on his website, but has modified his language in discussing it. At a rally Sunday night outside Detroit, he said he would&nbsp;"pause admissions from terror-prone regions of the world" until protections against terrorism are tightened.
