D.C. shooting suspect "radicalized" since coming to U.S., Noem says

• "I will say we believe he was radicalized since he's been here in this country," Noem said on NBC's Meet the Press. "We do believe it was through connections in his home community and state, and we're going to continue to talk to those who interacted with him, who were his family members, who talk to them."

Zoom out: The suspect came to the U.S. through a program for vulnerable Afghan nationals and those who aided American forces in the war, but the Trump administration has demanded additional vetting for a variety of immigrants since the shooting.

• Noem blamed the Biden administration's hasty withdrawal from Afghanistan for hindering the vetting process.
• "You have to have a stable government that will give you information, contacts, background information, and biometrics that you may need to identify that individual, their dates of service," she said.
• Attorney General Pam Bondi on Fox News Sunday blamed the Biden administration for a backlog of 1.5 million asylum applications needing review.

The other side: Sen. Mark Kelly (D-Ariz.) on CNN's State of the Union called the shooting "horrific."

• "There needs to be an investigation and find out why did this guy do this," he said.
• However, he criticized the Trump administration's immigration crackdown for "just breaking up communities" rather than targeting criminals.
• While he said vetting is necessary, Kelly also said many of the Afghan immigrants who were brought to America "provided a valuable service to the United States of America."

On Fox News "Sunday Morning Futures," Border Czar Tom Homan predicted "most of them will end up being deported" after additional vetting.
