House passes bill to bar Syrian refugees from U.S. without more vetting

The House passed a bill Thursday to halt the admission of Syrian refugees into the U.S. until they undergo the toughest vetting process ever developed for people fleeing a war-torn nation.
The legislation, passed by a vote of 289-137, was rushed through in response to last week's terrorist attacks in Paris.
One of the terrorists is believed to have entered Europe through Greece with a group of Syrian refugees, sparking calls by congressional leaders to "pause" the flow of refugees into the U.S. from Syria and Iraq.
The bill requires the nation's three top security officials - the Homeland Security secretary, FBI director, and national intelligence director - to certify to Congress that each Syrian or Iraqi refugee is not a security threat before the refugee can be admitted into the U.S.
