A senior House Republican said Monday the Trump administration has resorted to implementing “catch and release” at the border instead of after being held for several weeks due to the sheer number of migrants illegally crossing from Mexico into the U.S. and claim to have a credible fear of returning home.

“Law enforcement doesn’t have the resources to process and detain the crushing influx of migrants arriving at the border. As a result, they are directly releasing migrants into the United States – catch and release,” House Homeland Security ranking member Mike Rogers, R-Ala., said in a statement Monday. “Without Congressional action, the situation on the ground poses a serious threat to human life and national security.”

A few weeks ago, Customs and Border Protection’s Border Patrol entity stopped funneling all migrants apprehended to Immigration and Customs Enforcement for the maximum 20-day detainment.

Instead, an unspecified number of migrants were released by agents in the Rio Grande Valley, Texas, El Paso, Texas, and Yuma, Ariz., communities.

Last April, the White House said it was forced to catch and release migrants, though that was after they were transferred from CBP to ICE. Now those encountered on the border are documented by agents and let go.

“Law enforcement is forced to resort to catch and release because they do not have the resources to process, transport, and detain the record number of migrants they are apprehending,” Rogers’ committee spokeswoman Nicole Hager said in an email.

Acting ICE Director Ronald Vitiello last week said the releases are "not really different" than what CBP did in the mid-2000s. Back then, Border Patrol agents were arresting nearly 100,000 people per month and would release some out the back door of stations.

Border Patrol expects to apprehend 100,000 illegal border-crossers in March, the majority of whom are families and unaccompanied children from countries other than Mexico and must be handled differently than single adults from Mexico.
