The Laken Riley Act directs Immigration and Customs Enforcement to detain illegal immigrants arrested or charged with theft-related crimes, or those accused of assaulting a police officer.

President Donald Trump on Wednesday will sign the Laken Riley Act into law as his administration’s first piece of legislation. It mandates the detention and potential deportation of people in the U.S.

The Laken Riley Act, named for the slain nursing school student who was attacked and killed by a Venezuelan citizen who had entered the U.S. illegally, is the first legislative win of Trump's second term.
