President Donald Trump has justified sending National Guard troops into U.S. cities as part of an effort to combat crime and support local law enforcement. The CBO said continued deployments to those cities would cost about $93 million per month. For further possible deployments down the road, the CBO estimates deploying 1,000 National Guard personnel to a U.S. city in 2026 would cost $18 million to $21 million per month, depending on the local cost of living. National Guard troops are expected to remain deployed in Washington throughout 2026, according to a memo reviewed by The Associated Press earlier this month. A California federal judge in January ruled that the Trump administration “willfully” broke federal law by sending National Guard units to the Los Angeles area.
