WASHINGTON: A former US immigration official said Monday that training for federal agents was “deficient, defective and broken,” adding to pressure on President Donald Trump’s sweeping crackdown.

Ryan Schwank resigned this month from his job teaching law at the US Immigration and Customs Enforcement (ICE) training academy in Glynco, Georgia, after he said he was instructed to teach new recruits to violate the US Constitution.

The fatal shooting of two American citizens in Minneapolis in January reignited accusations that agents enforcing Trump’s militarized immigration operation are inexperienced, undertrained and operating outside law enforcement norms.

The administration scaled back the deployment after the killings of Renee Good and Alex Pretti in broad daylight by officers sparked mass protests and widespread outrage.

Schwank told a forum hosted by congressional Democrats on Monday that he “received secretive orders to teach new cadets to violate the Constitution by entering homes without a judicial warrant.”
