President Donald Trump has built his presidency around stretching the bounds of presidential authority, and his response to protests over an immigration crackdown in Los Angeles is no exception.

Gov. Gavin Newsom, in an address called “Democracy at a Crossroads,” called on Americans to stand up to President Trump.

Trump left open the possibility of invoking the Insurrection Act, which authorizes the president to deploy military forces inside the U.S. to suppress rebellion or domestic violence or to enforce the law in certain situations. It's one of the most extreme emergency powers available to a U.S. president.

After the Trump administration sent Marines and National Guard troops to Los Angeles in response to the protests against immigration enforcement, Gov. Ron DeSantis proposed adding another group to the mix: the Florida State Guard.

Another 2,000 National Guard troops along with 700 Marines are headed to Los Angeles on orders Monday from President Donald Trump, escalating a military presence local officials and Gov. Gavin Newsom don’t want and the police chief says creates logistical challenges for safely handling protests.

It's been five days since anti-ICE demonstrations erupted in Los Angeles, some turning violent between protesters and law enforcement officers, prompting President Trump to deploy National Guard troops and hundreds of Marines.

U.S. District Judge Charles Breyer, a former Watergate prosecutor, will decide whether Trump had the legal authority to federalize 4,000 California National Guard troops.

Dozens arrested in Los Angeles as anti-ICE protests turn violent, with charges including assault on police and attempted murder as National Guard troops deploy.
