Federal troop deployments to US cities cost taxpayers $496M and counting

The Trump administration's high-profile deployment of federal troops to six U.S. cities has cost taxpayers roughly $496 million through the end of December, and continued deployment could cost over $1 billion for the rest of the year, according to new data from the nonpartisan Congressional Budget Office. 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. Critics of the move argue the deployments undermine state and local authority and exceed the president’s authority under the Constitution.
