Brown agreed to send troops on the mission last week but said troops wouldn’t be used to enforce immigration laws.
The move sparked a back-and-forth between California and the federal government about how the state’s guard would fit into the overall mission.
The president tweeted Tuesday: “Looks like Jerry Brown and California are not looking for safety and security along their very porous Border. He cannot come to terms for the National Guard to patrol and protect the Border. The high crime rate will only get higher. Much wanted Wall in San Diego already started!”
During a press briefing Tuesday morning, Brown said, “I’m trying to deal with a human crisis. We have people being deported whose children don't even have any parents. businesses and communities being disrupted.”
