The Pentagon's expected deployment of as many as 1,500 active duty troops to aid with securing the southern border in the coming days will likely be followed by further action, according to a U.S. Army Special Forces veteran.
Even though law prohibits troops from enforcement duties under the Posse Comitatus Act, President Donald Trump has directed through executive order that the incoming secretary of defense and homeland security chief report back within 90 days if they think an 1807 law called the Insurrection Act should be invoked. Such law would allow those troops to be used in civilian law enforcement on U.S. soil.
