Donald Trump again fails to screen out the falsehood in oft-repeated claim on Syrian refugees

Immigration has been the cornerstone of Donald Trump's campaign, so it was not surprising he raised the issue again in his acceptance speech for the Republican presidential nomination. He attacked Hillary Clinton’s plans to accept refugees and promised to choke off all immigration from countries who might be sending terrorists to the United States.

"We must immediately suspend immigration from any nation that has been compromised by terrorism until such time as proven vetting mechanisms have been put in place," he told the crowd in Cleveland on July 21.

"My opponent has called for a radical 550 percent increase in Syrian, think of this, think of this. ... A 550 percent increase in Syrian refugees on top of existing massive refugee flows coming into our country already under the leadership of President Obama," he said. "She proposes this despite the fact that there’s no way to screen these refugees in order to find out who they are or where they come from. I only want to admit individuals into our country who will support our values and love our people."

We've addressed these issues in several other fact-checks. The bottom line: Trump is wrong to suggest that screening isn't done and correct when he says Clinton has recommended a 550 percent increase.
