Immigration union begs Ryan to help end 'national crisis' on border

House Speaker Paul Ryan has landed himself in hot water with a U.S. immigration union that claims Ryan isn't doing enough to help solve a crisis at the border.

The Washington Examiner obtained a letter the National Immigration and Customs Enforcement Council sent to the House speaker Tuesday, blasting Ryan's support of an omnibus spending bill in 2015.

"You have not spoken out about any of the issues confronting our officers or the threat to public safety presented by the lawless immigration policies of the Obama Administration," union president Chris Crane wrote.

The union has targeted the White House in the past, and has sued the president over his Deferred Action for Childhood Arrivals program and the Dream Act, which it claims has had a "significant role in sparking the nation's border crisis."

"Foreign nationals flood across the border because they have been led to believe that if they can make it here, they can stay," the letter reads. "Children crossing our border are molested and perish. Any political leader who truly cares about these children will stop the rhetoric and begin working with law enforcement to develop sound immigration policy to end the crisis on our nation's border."

The National ICE Council is part of the broader federal employee union, representing about 7,600 officers and other members of the U.S. Immigration and Customs Enforcement across the country. The group's president has appeared alongside Donald Trump at a campaign rally and criticized Sen. Marco Rubio's immigration legislation in the past.

The letter also warned Ryan against bringing up criminal justice reform legislation the union fears could lead to the release of detained undocumented immigrants.

The National ICE Council has requested a press conference with Ryan within the next week.
