The city and county of Los Angeles, along with several municipalities in Southern California, are seeking to join a lawsuit filed against the Trump administration over recent immigration raids.

Trump called National Guard troops and U.S. Marines into Los Angeles in June in response to protests against the immigration raids, marking an extraordinary use of military force to support civilian police operations within the United States. The raids are part of the Republican president's hardline approach toward immigration.

Los Angeles is at the center of the Trump administration's immigration enforcement efforts. As a judge weighs in, how the standoff is resolved could have implications for the rest of the U.S.
