The Trump administration announced on Tuesday that it has suspended the processing of all immigration applications from 19 countries, including Afghanistan and Somalia, citing national security and public safety concerns. The action comes a week after an Afghan national was arrested for shooting two National Guard members near the White House, killing one and critically wounding the other. The suspension includes green card and U.S. citizenship processing, according to a memorandum.

The House Homeland Security Committee will hear testimonies from leaders of law enforcement associations regarding how anti-law enforcement rhetoric is fueling violence against officers nationwide.
