Obama asks for review of K-1 fiance visa program

President Barack Obama has asked the U.S. Department of Homeland Security and the State Department to review the K-1 fiance visa program that was used by a couple responsible for a mass shooting in California last week, a White House official said on Sunday.

In a televised address, Obama said he had ordered a review of the "visa waiver program" used by Tashfeen Malik to enter the United States. But a White House official confirmed Obama misspoke, meaning to say "visa program."

The U.S. government separately is making a series of changes to its visa waiver program to screen travelers more closely from 38 countries who can enter the United States without visas.
