U.S. National Guard troops patrolling the streets of Washington D.C. as part of what President Donald Trump said was his crackdown on crime will begin carrying weapons on Sunday night, two officials said.

In the first week after Trump’s DC police takeover, the city saw a moderate drop in reported crime — and a far larger surge in arrests of immigrants, a CNN analysis found.
