Hundreds of Marines sent to Los Angeles in response to anti-immigration raid protests are set to head home after a little more than a month in the city, ending a controversial domestic deployment of active-duty troops not seen in more than three decades.

The departure of the Marines follows the removal of hundreds of other National Guard soldiers who were part of President Trump’s deployment to Los Angeles.

The Pentagon has ordered U.S. Marines to leave Los Angeles after more than a month in the city. The 700 Marines were deployed on June 9 during protests against the administration’s immigration policies.
