The troop reassignment still needs approval from the U.S. Department of Defense.
According to Newsom's office, only 100 of the 360 National Guard troops now stationed at the border will remain there. "And California will not be part of this political theater".
Gavin Newsom ordered the withdrawal of most of the National Guard troops now deployed at the state's southern border in a public rebuke to President Donald Trump. Another 110 will be assigned to wildfire preparation duty. He said he had yielded because he got the federal government to ante up for it and the members were still supervised by the state.
Both Newsom and Grishman are new governors this year whose predecessors approved Trump's plan to have troops at the border.
Just a month into his governorship of the nation's most populous state, Newsom has sparred with Trump on immigration and other issues.
Gov. Gavin Newsom speaks in Sacramento, Calif. last month. On his first day on the job, Newsom directed the California National Guard Adjutant to prepare a "menu of options" to end the participation in Trump's initiative.
"This will not be a mission to build a new wall", Brown wrote at the time in a letter to Trump administration officials. "It will not be a mission to round up women and children or detain people escaping violence and seeking a better life". The troops can not act to enforce the law or to make arrests.
Trump and Democrats in Congress have been engaged in a contentious battle over his proposed U.S./Mexico border wall, which would extend all the way from the Pacific Ocean to East Texas.
Last week President Trump tweeted that he is sending additional US military to the Southern Border, saying, "Tremendous numbers of people are coming up through Mexico in the hopes of flooding our Southern Border". They can not act as a police force or make arrests.
Then-California Senate leader Kevin De Leon and 26 state legislators urged Brown to end the National Guard agreement.
Newsom's reversal of Brown's deployment is no surprise. Newsom had been very critical of the move while on the campaign trail in 2018.
"The border "emergency" is a manufactured crisis," Newsom said in prepared remarks.
"What's appropriate, what would be inappropriate, what was our commitment under the executive order Gov".
A spokesman for Newsom said his office will separately request federal funds for the expansion of the state's counterdrug task force program, The Los Angeles Times reported.
He added: "I can assure you I have not deviated from my previous statements in terms of my desire to move in a different direction".
