The additional staffing would allow the Guard to support statewide law enforcement operations, Brown said but emphasized the guardsmen would not detain border jumpers or other illegal aliens. "At some point that might come together", said Ronald D. Vitiello, acting deputy commissioner of Customs and Border Protection, which oversees both the Border Patrol and the ports of entry.

Brown elicited rare and effusive praise from President Donald Trump last week for pledging 400 troops to the Guard's third large-scale border mission since 2006.

The state's position infuriated some federal officials because the restrictions California officials wanted to impose on what the state's troops would not do were considered onerous, the officials said.
Trump wants to send up to 4,000 troops to the border and has commitments for about 2,400 from those states and California. Nor has California explained what criteria it would use to distinguish between immigration-related tasks and tracking transnational gangs, human traffickers and drug smugglers.
The Democratic governor cast his decision as a welcome infusion of support paid for by the USA government to fight transnational criminal gangs and drug and firearms smugglers. Texas National Guard members are already doing aerial and ground surveillance.
Other border state governors, though, have supported Trump's plans to deploy the National Guard to the border. General Daniel R. Hokanson, the National Guard Bureau's vice chief.
