A federal judge in San Francisco is weighing whether the Trump administration violated federal law by sending National Guard troops to accompany federal agents on immigration raids in Southern California.

A general has testified that National Guard troops repeatedly rehearsed their role in an operation at a Los Angeles park intended as a show of force against people protesting immigration raids.

A federal judge is hearing arguments on whether military troops deployed this summer by the Trump administration to Los Angeles violated a federal law that bars troops from conducting law enforcement duties within the country.

After a week of protests over federal immigration raids, about 200 Marines have moved into Los Angeles to guard a federal building and personnel in the city.

About 500 of the National Guard troops deployed to the Los Angeles protests have been trained to accompany agents on immigration operations, the commander in charge said Wednesday.

The Los Angeles Police Department has made nearly 400 arrests and detentions since Saturday in connection to immigration protests.

Dozens of mayors from across the Los Angeles region banded together to demand that the Trump administration stop the stepped-up immigration raids that have spread fear across their cities and sparked protests across the U.S. They also called on President Donald Trump to pull back from using troops alongside immigration agents during the raids.
