Attorney General Sessions gave a speech at the US-Mexico border on Tuesday, promising a new era of immigration enforcement and a crackdown on those already in the United States illegally, reports ABC news.

Speaking to the press, Sessions outlined a series of new guidelines that would harshly prosecute drug cartels, criminal organizations, and illegal immigrants entering in to the United States from Mexico. 

The Attorney General also threatened 'sanctuary cities' and others that choose to ignore the new federal rules with severe penalties and financial pressure.

“When we talk about MS-13 and the cartels, what do we mean? We mean criminal organizations that turn cities and suburbs into war-zones, that rape and kill innocent citizens, and who profit by smuggling poison and other human beings across our borders,” Sessions told Customs and Border Protection officers. “Depravity and violence are their calling cards, including brutal machete attacks and beheadings.”

The Trump administration and Attorney General Sessions plan to invest hundreds of millions of dollars in to the Customs and Border Protection agency, hiring over 60 federal prosecutors, 40 U.S. Border Marshals, and thousands of new immigration agents.

"This is a new era. This is the Trump era," he said. "The lawlessness, the abdication of the duty to enforce our immigration laws, and the catch and release practices of old are over."
