Governor Gavin Newsom of California announced that his state plans to file a lawsuit Monday against Donald Trump for mobilizing the National Guard over the weekend to quell immigration-related protests in Los Angeles.

In announcing the lawsuit, Attorney General Rob Bonta called the president's move to federalize the National Guard an "infringement" on state sovereignty.

President Donald Trump further tightened his grip on Los Angeles on Monday by deploying a fresh batch of National Guard troops to quell protesters. Trump has mobilized an additional 2,000 National Guard as protests against immigration raids dragged into their fourth day,
