California state senator Nancy Skinner is asking the White House to release First Lady Melania Trump's immigration documents in light of the president's recent executive orders on immigration.

Skinner (D-Calif.) told POLITICO California that transparency is needed regarding the First Lady's immigration status.

"No one in the Trump operation has released any of the documentation to indicate what was the circumstance, or whether she had full legal status,'' Skinner told POLITICO. "We only know they had a lawyer look at whatever papers she chose to give."

Melania Trump, who came to New York City from Slovenia in 1996 to pursue her modeling career, was the subject of an AP investigation last November. The investigation found that she had been paid for 10 modeling jobs in the U.S. before she had legal permission to work. Her visa allowed her to be in the country and search for employment, but it did not permit paid work at that time.

Sen. Skinner's demand comes as part of her protest against Trump's executive order on sanctuary cities. The order blocks all "federal grants, except as deemed necessary for law enforcement" to sanctuary cities.

San Francisco City Attorney Dennis Herrera has said that the order will be challenged in court.

"This executive order tries to turn cities and states into U.S. Immigration and Customs Enforcement. That's against the law," Herrera said. "Cities cannot be coerced into becoming the deportation arm of the federal government."
