San Diego, March 13 (RHC)--Demonstrators against Donald Trump are expected to mark his first visit to California as president amid growing tensions between his administration and the state over immigration enforcement.

Trump will visit eight towering prototypes of his planned border wall with Mexico Tuesday before addressing Marines in San Diego and attending a fund-raiser in Los Angeles.

About 250 people protested Trump in San Diego on Monday.

Protests are also being planned across the border in Tijuana, Mexico, when Trump will examine the 30-foot-tall prototypes built along the international border to fulfill his signature campaign promise. Trump has insisted Mexico pay for the wall but Mexico has adamantly refused to consider the idea.

San Diego is the largest city on the U.S.-Mexico border to formally oppose his plans, passing a resolution in 2017.

Immigrant activists, church leaders and elected officials held a press conference at the city's historic Chicano Park to call for demonstrations to show border communities do not support a wall. Standing in front of murals of Mexican revolutionaries and other Latin American icons, they chanted "We reject your hate! We don't need your racist wall!"
