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.
"The federal government has not yet responded", Keegan said in an emailed statement.
The government of California officially rebuked the Trump administration's decision to deploy the National Guard to the southern border Monday; saying federal plans had their troops working "too closely" with immigration enforcement.
Brown has been the only holdout among border state governors, as Texas, New Mexico and Arizona - all led by Republicans - moved quickly to send personnel.
Officials said that Operation Guardian Support is created to increase deterrence and border security capabilities. The state informed federal officials that its troops will not be allowed to fix vehicles, operate remote surveillance equipment, operate radios, or provide other "mission support" to border agents.

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. He said that talks with California are ongoing. State insiders with knowledge of the talks spoke on condition of anonymity because they were not authorized to discuss the matter.
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.
