Military-style vehicles and National Guards troops have blocked a portion of 4th Street in front of the Ronald Reagan Federal Building and Courthouse.

A cloud of uncertainty is hanging over Los Angeles, where questions remain over the role that Marines and National Guard troops will play after being called in by President Donald Trump amid protests over immigration raids in the city.
