President Donald Trump has granted federal immigration agents "total authorization" to defend themselves following clashes with protesters during a recent enforcement operation at a cannabis farm in California.

Federal law enforcement officials fired tear gas and rubber bullets at protesters Thursday during a large immigration raid in Ventura County at one of California’s largest and most notable cannabis farms, according to a local mayor at the scene.

Jaime Alanis, 57, worked on a farm in Camarillo for 10 years before Thursday’s ICE raid, according to his family.
