President Donald Trump ordered a pause in the U.S. Diversity Visa lottery after investigators found the Brown and MIT shootings suspect had entered the country through the program, following an initial suspension announced by Homeland Security Secretary Kristi Noem.Authorities identified the suspect as Claudio Manuel Neves-Valente and said he is accused of killing two Brown students, wounding nine others and fatally shooting MIT professor Nuno F.G. Loureiro; investigators reported Neves-Valente died of an apparently self-inflicted gunshot wound and that officers recovered two firearms.Officials noted Neves-Valente first came on an F-1 student visa around 2000, later won a Diversity Visa in 2017 and became a lawful permanent resident, and legal experts say the administration’s pause is likely to face court challenges because winners still must pass vetting.
