"Interior enforcement of our nation's immigration laws is critically important to the national security and public safety of the United States. Aliens who illegally enter the United States and those who overstay or otherwise violate the terms of their visas have violated our nation’s laws and can pose a threat to national security and public safety. This is particularly true for aliens who engage in criminal conduct in the United States. We are charged with faithfully executing the laws of the United States and we will not exempt classes or categories of removable aliens from potential enforcement. The Executive Order No. 13768 entitled “Enhancing Public Safety in the Interior of the United States” directs our Department and agencies to enforce the law, and we will do so professionally and humanely.
