House Republicans plan to take their first shot at President Obama’s immigration directive on Dec. 3, when a committee will examine how the reduction in deportations will affect border security.

Homeland Security Committee Chairman Michael McCaul, R-Texas, has summoned Homeland Security Secretary Jeh Johnson to testify on how the federal government is preparing for the new directive, which will end the threat of deportation for more than 4 million people living in the United States illegally.
