Sessions makes clear: It's 'Trump era' of immigration enforcement

The attorney general warned of strict enforcement of the laws.

"For those that continue to seek improper and illegal entry into this country, be forewarned. This is a new era. This is the Trump era," Sessions said today in remarks to immigration officials in Arizona. "The lawlessness, the abdication of the duty to enforce our immigration laws and the catch-and-release practices of old are over."

"This is no accident," he said, citing a drop in unauthorized immigrants entering the country through the border with Mexico. "This is what happens when you have a president who understands the threat, who is not afraid to publicly identify the threat and stand up to it and who makes clear to law enforcement that the leadership of their country finally has their back."
