National Guard shooting suspect radicalized in US, homeland secretary says

U.S. 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 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.

Authorities identified Lakanwal, 29, as the suspect in a Wednesday shooting that took place just blocks away from the White House and which killed one National Guard member and critically wounded another. After the shooting, U.S. President Donald Trump's administration pointed to a lack of vetting of Afghans and other foreign nationals during the term of former President Joe Biden, although Lakanwal was granted asylum under Trump.
