President Donald Trump on Sunday threatened to send National Guard troops to Baltimore, saying the city is “out of control” after Maryland Governor Wes Moore invited him to walk local streets and discuss public safety. In a Truth Social post, the president wrote that, if Moore needs “help,” he would “send in the troops,” echoing the federal deployment now under way in Washington, D.C. Moore, a Democrat, rejected the idea, noting that Baltimore’s homicide tally fell 24 percent last year and that overall violent crime dropped nearly 8 percent. He accused the president of relying on outdated “tropes” rather than joining local leaders working to sustain those improvements. Trump’s warning extends a broader law-and-order campaign that has already put more than 2,000 armed Guard members on the streets of the nation’s capital and earlier sent about 4,000 troops to Los Angeles. The president said Chicago could be “next,” drawing resistance from Democratic officials there and elsewhere. The president also suggested he may reconsider the $2 billion in federal funds Congress approved to rebuild Baltimore’s Francis Scott Key Bridge, which collapsed in 2024, further heightening tensions with Maryland officials.
