Last week, Trump said he’s considering withdrawing Immigration and Customs Enforcement (ICE) officers from the state because of its “sanctuary cities,” where local law enforcement refuse to cooperate with federal immigration law.

The construction of a wall along the U.S.-Mexico border was a signature campaign promise of Trump’s. Since taking office, officials have at various times indicated the wall could include fencing in some portions.

Eight prototypes of the wall are being built near San Diego.

During the campaign, Trump repeatedly claimed Mexico would pay for the wall, but Mexico has refused to do so. That disagreement recently prompted Mexican President Enrique Peña Nieto to cancel his plans to visit the White House in the coming weeks.

A poll late last year found roughly two-thirds of California voters disapproved of Trump's job performance.
