President-elect Donald Trump has famously vowed to build a wall at the Mexican border, though the other day he suggested, in some areas, it might be a fence. All that talk might have led more illegal immigrants to try to get into the U.S. now prompting a deployment of more order patrol agents.

FOX's Eben Brown has the details from Miami:

About a 150 extra border patrol agents are being deployed to the U.S.-Mexico line in South Texas, in Arizona and even California following a very recent spike in the number of people apprehended trying to cross into the United States illegally, including whole families and unaccompanied children.

U.S. Homeland Security secretary Jeh Johnson says more than 40,000 illegal migrants are being held in detention centers, much more than usual, and that after processing, many will likely be returned to their countries of origin.
