White House threatens veto for House GOP immigration measure.

The White House has threatened to veto a House Republican bill called the Secure the Border Act, aimed at cracking down on the flow of migrants at the US-Mexico border, arguing it would worsen elements of the immigration system. The GOP bill calls for building barriers along hundreds of miles of the southern border, cutting a program that allows certain migrants to stay in the US for up to two years, and increasing requirements for verifying the immigration status of certain workers. The bill stands little chance of gaining traction in the Democratic-controlled Senate.
