The Secretary shall immediately take all appropriate actions to ensure the detention of aliens apprehended for violations of immigration law pending the outcome of their removal proceedings or their removal from the country to the extent permitted by law. 

The Secretary shall issue new policy guidance to all Department of Homeland Security personnel regarding the appropriate and consistent use of lawful detention authority under the INA, including the termination of the practice commonly known as "catch and release," whereby aliens are routinely released in the United States shortly after their apprehension for violations of immigration law.
