The California Department of Transportation has confirmed the discovery of five official-looking signs declaring the state as an "official sanctuary state," or one in which federal immigration policies will not be honored.

One sign posted on Interstate 15 at Mountain Pass near the California-Nevada border has been taken down, Caltrans spokesman Mark Dinger told the Washington Examiner on Tuesday.

A second sign was confirmed attached to a highway sign on Interstate 40 in Needles, Calif., west of the California-Arizona border. A crew of transportation employees has been dispatched to take it down.

Dinger said there are unconfirmed reports of up to three more signs posted around the Golden State, including at the California-Oregon border. He also said they were made of paper even though they look like metal fixtures.

One of the blue signs was posted below an official "Welcome to California" sign and stated "Official Sanctuary State ... felons, illegals and MS13 welcome ... Democrats need the votes" near the bottom.

“For safety reasons, Caltrans does not permit any unauthorized signs in the state right of way. If we haven’t done so already, Caltrans crews will take steps to remove them," the department said in a statement provided to the Washington Examiner.

Dinger said it's not clear who is responsible for posting the signs across the state and did not share whether law enforcement will take action and investigate.
