The federal agency that oversees U.S. borders will soon begin releasing the number of illegal immigrants who it believes evaded arrest while sneaking over the border from Mexico, the Washington Examiner has learned.

Prior to last week’s election, the Department of Homeland Security’s U.S. Customs and Border Protection approved a plan to start publishing the number of people whom Border Patrol agents were unable to arrest while patrolling the border. The monthly figure is expected to be in the thousands based on federal statistics from recent years that show the average 30,000 to 60,000 people arrested each month make up about 75% of the total who crossed. The numbers will also include how many people attempted to enter the United States illegally but turned back to Mexico.
