Rep. Pete Sessions (R-TX) is urging President Donald Trump to reevaluate his administration’s immigration policies, arguing that the White House has not clearly defined its approach and distinguishing between dangerous criminals and other people living in American cities.

During Tuesday’s broadcast of NewsNation’s Morning in America, Sessions said Trump would need to reconsider some of his administration’s positions on immigration. His comments add to pressure on the administration from Republicans who are questioning its approach to a central campaign issue.

Asked what he wanted to hear from the president, Sessions called for less government and greater reliance on free markets before turning to immigration.

“He’s going to have to reevaluate some of the ideas that he thinks that he and the administration have about immigration,” Sessions said. “I think that immigration is something we have not been able to clearly understand as well.”

Sessions then questioned the administration’s emphasis on removing criminals, arguing that dangerous offenders should be distinguished from other people living in cities.

“I think that he has told us, I’m going after criminals. But I think that criminals and dangerous criminals to cities are different than just people who live there,” he said.

The remarks risk muddying the distinction between enforcing immigration law and determining which illegal immigrants pose the greatest public safety threat. Federal immigration enforcement is not limited to people convicted of violent crimes, and illegal entry or remaining in the country unlawfully can itself violate federal law.

While Sessions did not provide further details in the remarks quoted, his call for Trump to reevaluate the administration’s approach puts him at odds with conservatives who argue that immigration enforcement must remain consistent and that the federal government should not allow unlawful status to become an automatic shield against removal.

The comments come as the Trump administration faces continuing debate over how to carry out its immigration agenda while addressing public safety concerns and enforcing federal law.
