The new picture of law enforcement in the U.S. capital began taking shape Tuesday as some of the 800 U.S. National Guard members deployed by the Trump administration began arriving.

The city’s police and federal officials took the first steps Tuesday in an uneasy partnership to reduce crime in what President Donald Trump called — without substantiation — a lawless city.

The National Guard was officially deployed in Washington, D.C., on Tuesday night, joining hundreds of federal law enforcement agents in the Capitol during the second day of President Donald Trump’s controversial crime crackdown, which was launched amid a 30-year low in violent crime for the D.C.
