The White House suspended the green card lottery program after it was discovered that the Brown University shooting suspect entered the country through it. The decision was made at the direction of President Donald Trump, according to Homeland Security Secretary Kristi Noem.

"At the direction of the President, I am immediately ordering Citizenship and Immigration Services to suspend the DV1 program so that Americans are no longer harmed by this harmful program," Noem wrote on social media.

The minister clarified that 48-year-old Portuguese national Claudio Neves Valente, whom authorities believe is responsible for the incident, arrived in the United States in 2017 as a winner of the immigration lottery.

The shooting at Brown University in Providence, Rhode Island, occurred on the evening of December 13. Two people were killed and nine others were injured, according to Providence Police Chief Oscar Perez.

A green card (literally, "green card," officially the United States Permanent Resident Card) is an identification document that confirms permanent residence in the United States and allows non-citizens to legally work. It can be obtained through a special lottery run by the US government since the 1990s. The lottery is aimed at attracting immigrants from countries underrepresented in the United States.
