Military-style vehicles and National Guards troops have blocked a portion of 4th Street in front of the Ronald Reagan Federal Building and Courthouse.

The U.S. military deployments that President Donald Trump has directed in response to unrest in Los Angeles are expected to cost $134 million for 60 days of operations, a senior defense official said at a hearing Tuesday.

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.

An uptick in activity at the Ohio National Guard site in Akron is likely part of routine training, the governor's spokesman said.

Local officials and Governor Gavin Newsom don’t want the military presence and the police chief has said it creates logistical challenges for safely handling protests.

HOW WE GOT HERE: The protests erupted after Immigration Customs Enforcement (ICE) officers on Friday carried out raids in three locations across L.A., where dozens of people were taken into custody. Newsom called the raids “chaotic federal sweeps” that aimed to fill an “arbitrary arrest quota.”

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.

President Donald Trump's deployment of the National Guard to Los Angeles in response to immigration protests is the latest in a long history of U.S. elected officials sending troops in hopes of thwarting unrest connected to civil rights protests.
