When President Donald Trump put 2,000 National Guard troops under his control on Saturday night and ordered them into Los Angeles, it was billed as an urgent response to quell protests. But it was also a move long in the making.

Newsom filed a lawsuit Monday in response to Trump ordering the deployment of roughly 4,000 National Guard members to Los Angeles following protests over his stepped-up enforcement of immigration laws. They were originally called in to protect federal buildings, and the president later ordered the deployment of 700 Marines.
