The Trump administration has revoked the visas of six foreign nationals accused of mocking the assassination of conservative activist Charlie Kirk. The State Department cited disturbing social media posts as the reason for the action, targeting individuals from Argentina, South Africa, Mexico, Brazil, Germany, and Paraguay. The move comes after President Trump posthumously awarded Kirk the Presidential Medal of Freedom, with his widow and parents attending the ceremony. Critics, including civil rights groups and legal advocates, have condemned the administration's actions as an attack on freedom of speech, raising concerns about the broader implications for noncitizens and current visa holders.
