Federal agents turned up in downtown Los Angeles, where Gov. Gavin Newsom was delivering a speech, and detained at least one person in the latest high-profile immigration enforcement operation in the city.

Federal agents conducted an immigration enforcement operation Thursday in the Little Tokyo area, outside the venue where Gov. Gavin Newsom held a news conference on redistricting in California.

California Governor Gavin Newsom’s office posted a video on social media showing agents gathering outside the conference, drawing condemnation from the governor and Los Angeles mayor.
