A new front in the battle between California Gov. Gavin Newsom and the Trump administration has opened over a video in which Centers for Medicare and Medicaid Services Administrator Dr. Mehmet Oz visits Los Angeles and alleges members of its Armenian community orchestrated large-scale health care fraud.

The dayslong public scuffle on social media escalated on Thursday evening, when Newsom announced his office was filing a civil rights complaint with the U.S. Department of Health and Human Services accusing Oz of discrimination.

Newsom’s office argued in the complaint that Oz “spewed baseless and racially charged allegations” that risked chilling participation in hospice and home care programs among the community targeted. The governor’s office noted the claims had “already caused real-world harm” by dampening business at an Armenian bakery that is shown in the video.
