US officials say Rahmanullah Lakanwal, an Afghan man accused of shooting two National Guard members near the White House, may have been radicalized after arriving in the United States. Lakanwal, who entered the country in 2021 during the Afghan airlift, is charged with first-degree murder in the attack that killed one guardsman and critically injured another. Homeland Security Secretary Kristi Noem stated that authorities believe Lakanwal's radicalization occurred through local connections. The incident has sparked debate over immigration policies and vetting procedures, with former President Donald Trump calling the shooting an act of terror and criticizing the previous administration's handling of Afghan arrivals.
