Trump says he would implement 'extreme vetting' of immigrants

  Republican presidential hopeful Donald Trump on Monday unveiled his anti-terrorism plan, saying he would implement "extreme vetting" of immigrants as one way to protect the United States and suspend immigration from certain countries."We should only admit into this country those who share our values and respect our people," Trump said in a speech. "In the Cold War, we had an ideological screening test. The time is overdue to develop a new screening test for the threats we face today. I call it extreme vetting."
