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,

The additional National Guard troops will join the Marines who are deployed to quell clashes between demonstrators and law enforcement after a series of immigration raids in the city.

The last time the National Guard was activated without a governor’s permission was in 1965, when President Lyndon B. Johnson sent troops to protect a civil rights march in Alabama.
