President Trump’s decision to send troops into an American city comes just days before a rare military display in the nation’s capital.

The power of the US military will be sharply on display this weekend – on two different coasts and in two very different ways.

A federal court hearing is scheduled for Thursday challenging Trump's use of the National Guard and Marines to support immigration raids in Los Angeles. California leaders warn that the military intervention is the onset of a much broader effort by Trump to overturn norms at the heart of America's political system.
