The Trump administration reportedly plans to mobilize up to 1,700 National Guard troops across 19 states in the coming weeks to support its immigration and anti-crime crackdowns, a dramatic expansion of the controversial operation that’s seen federal agents and Guard troops carrying out activities across Washington, D.C.

The troops, who will largely be activated across Republican-controlled states, will serve in support of the administration’s Immigration and Customs Enforcement operations, as well as other law enforcement priorities, according to comment from unnamed Pentagon officials and documents obtained by Fox News.
