The suspected gunman who shot two National Guardsmen near the White House in Washington, D.C. on Wednesday has been identified as 29-year-old Rahmanullah Lakanwal from Afghanistan. He entered the United States under the Biden administration’s Operation Allies Welcome during the Afghanistan withdrawal and never left, according to sources. His visa expired a few months ago, leaving him in the U.S. illegally.

The suspect, who worked with U.S. government entities including the CIA as part of a partner force in Afghanistan, was among many unvetted Afghans brought into the country under the program. He is currently hospitalized and not cooperating with authorities, though some reports suggest he yelled “Allahu Akbar” before the attack.

The shooting occurred around 2:15 p.m. near the Farragut West Metro Station, just blocks from the White House. Authorities described it as a calculated ambush on National Guard troops on patrol. The suspect fired four rounds from a handgun, then used the guard’s weapon to shoot another, before being subdued by a third member.

The Biden administration has faced criticism for failing to properly vet Afghan nationals under its programs, with some 90,000 Afghans allowed entry into the U.S. through Operation Allies Welcome. A Justice Department inspector general report highlighted failures in processing refugees as the Taliban retook control of Afghanistan.

The suspect’s ties to U.S. government entities, including the CIA, were confirmed by intelligence sources, who stated he should never have been allowed to come here. The administration’s “catastrophic failures” left citizens and service members to endure ongoing fallout, they added.

As of now, no official motive has been revealed for the attack, which has sparked debate over the effectiveness of the Biden-era programs that brought him into the country.
