President Donald Trump signed the Laken Riley Act, named after the Georgia nursing student who was sexually assaulted and murdered by an illegal alien from Venezuela, into law on Wednesday.

The legislation, which marks the first proposal signed by Trump in his second term, requires Immigration and Customs Enforcement to detain illegal aliens who commit theft, burglary, larceny, and shoplifting offenses, as well as assault of a police officer or any other offenses resulting in serious bodily injury or death. The new legislation also has a provision that allows states to bring civil actions against federal officials who refuse to enforce immigration law.

Trump said during a signing ceremony that Jose Ibarra, the “vicious criminal who murdered precious Laken,” was both an illegal alien and a member of Venezuelan prison gang Tren de Aragua, who crossed the border illegally three years ago but was released into the country.

Ibarra had an extensive criminal record and several encounters with American law enforcement, for reasons that ranged from charges of endangering a child to shoplifting at a Walmart.

Trump continued by noting that the “cold-blooded criminal” went out “on that fateful morning hunting for women on whom to prey,” eventually encountering Riley while she was on a run. The commander-in-chief nevertheless added that “we’re going to show them who the hunter is.”

Allyson Phillips, the mother of Laken Riley, attended the bill signing along with members of their family, crediting Trump for contending for the legislation. She publicly honored Jesus Christ during her remarks, noting that “without his sacrifices, Laken’s story would have ended on that horrific day that she was taken from us, but because of him, we can continue living knowing that we will see Laken again.”
