As the military presence ramped up in Los Angeles, communities are preparing for the largest protests against Trump since he took office.

Amid a nationwide day of protest and following days of unrest in downtown Los Angeles, multiple simultaneous gatherings are expected to take place across Southern California on Saturday.

A new poll shows a partisan split on President Donald Trump's troop deployment to quell Los Angeles protests, with 86% of Republicans supporting while Democrats strongly oppose it.

The development comes a day after an appeals court temporarily blocked a judge’s order that directed President Trump to return control of the California National Guard.

A seaplane pilot, the sole occupant of the aircraft, made an emergency water landing Thursday at the Port of Los Angeles and was uninjured. The plane landed around 2:30 p.m., prompting a response from the U.S. Coast Guard, Los Angeles Port Police and Los Angeles Fire Department, according to LAFD spokesman Brian Humphrey.

Homeland Security Secretary Kristi Noem was in Los Angeles Thursday morning providing an update on immigration operations and protests in the area, when she was interrupted by Democratic Sen. Alex Padilla,

In San Francisco, the protest began at Dolores Park, where thousands gathered before marching nearly two miles to Civic Center Plaza. The crowd remained mostly peaceful throughout the day, waving signs critical of the Trump administration’s immigration policies and the deployment of the National Guard during recent protests in Los Angeles.
