Democratic presidential candidate Hillary Rodham Clinton on Sunday called for a drastic increase in the number of refugees the U.S. plans to take in.

"You know, look, we're facing the worst refugee crisis since the end of World War II and I think the United States has to do more and I would like to see us move from what is a good start with 10,000 to 65,000 and begin immediately to put into place the mechanisms for vetting the people we would take in, looking to really (emphasize) some of those who are most vulnerable," Clinton said on CBS's "Face the Nation."

Fellow Democratic candidate Martin O'Malley advocated for that same 65,000 earlier this month. Democratic candidate Bernie Sanders last week refrained from giving a number of refugees to take in, saying that the U.S. needs to help, but that the scope of who should be brought in is still unclear.
