During the second day of anti-Donald Trump demonstrations in California, activists surrounded the venue where Trump was scheduled to speak, with protests escalating to the point that even the Republican presidential candidate had some difficulty getting to his own event.

Earlier this month, the Trump campaign even outlined in a memo how he would implement his plan with Mexico's financial backing.

"We went under a fence and through a fence," Trump said at the luncheon. "And oh boy, it felt like I was crossing the border, actually."
