WASHINGTON: US authorities believe the Afghan immigrant accused of ambushing National Guard members in Washington, D.C., was not radicalized until after he came to the United States, Homeland Security Secretary Kristi Noem said on Sunday. Speaking on NBC’s “Meet the Press” and ABC’s “This Week,” Noem said authorities think that alleged shooter Rahmanullah Lakanwal was already living in Washington state when he became radicalized. Investigators are seeking more information from family members and others, Noem said.

The suspect had been recruited to Unit 03 of the Kandahar Strike Force, a former military commander told the BBC, coming to the US after the withdrawal.
