While accepting the Republican nomination for president on Thursday, Donald Trump said, "My opponent has called for a radical 550 percent increase in Syrian refugees on top of existing massive refugee flows coming into our country already under the leadership of President Obama. She proposes this despite the fact that there's no way to screen these refugees."

This is a pretty popular sound bite for Trump. But is it actually true? Well, sort of. President Barack Obama has called for the U.S. to accept 10,000 Syrian refugees, and Hillary Clinton wants a lot more.

"I would like to see us move from what is a good start with 10,000 to 65,000," Clinton told CBS last year.

Both of those numbers are still a drop in the bucket of the more than 4 million Syrian refugees. But Clinton has also said she's not suggesting blindly accepting just anyone from Syria like Trump suggests. And we already do have a pretty intense refugee vetting process in place.

"We also have to be vigilant in screening and vetting refugees from Syria, guided by the best judgment of our security and diplomatic professionals. Rigorous vetting already takes place while these refugees are still overseas, and it's a process that historically takes 18 to 24 months," Clinton said.
