The Department of Justice is sending 35 assistant United States attorneys to offices along U.S.-Mexico border to prosecute illegal entries into the country, and is also moving 18 immigration judges to the area.

“We are not going to let this country be overwhelmed. People are not going to caravan or otherwise stampede our border,” he told Fox Business Network on Wednesday afternoon. “We need legality and integrity in the system. […] We’re sending a message worldwide: Don’t come illegally. Make your claim to enter America in the lawful way.”
