California and the Trump administration have yet to finalize plans to send that state’s National Guardsmen to the border over concerns their work would be too closely tied to immigration enforcement, officials said Monday.

Talks between the Golden State and feds have hit a snag, according to Acting US Customs and Border Protection Deputy Commissioner Ronald D. Vitiello, saying that Sacramento views some of the tasks Guardsman might perform at the U.S.-Mexico border are “unsupportable.”

Despite this stalemate, Vitiello said talks between California and the White House are still ongoing.

California Gov. Jerry Brown got some rare praise from the president when he pledged to send 400 of the state’s National Guard troops to the border mission last week.

“California Governor Jerry Brown is doing the right thing and sending the National Guard to the Border. Thank you Jerry, good move for the safety of our Country!” the commander-in-chief tweeted four days ago.

But the Democratic leader said they would only go if they had nothing to do with immigration enforcement, which means Trump will likely revert to his previous view of Brown, whom he had mocked on Twitter.

“Governor Jerry ‘Moonbeam’ Brown pardoned 5 criminal illegal aliens whose crimes include (1) Kidnapping and Robbery (2) Badly beating wife and threatening a crime with intent to terrorize (3) Dealing drugs. Is this really what the great people of California want? @FoxNews,” he wrote on March 31.
