TIJUANA, Mexico (Reuters) - Protesters in Mexico burned effigies of Donald Trump and a border patrol agent on the U.S. border on Saturday, condemning President Donald Trump’s migration policies and urging Americans to reject him at the ballot box on Tuesday. A few dozen migrant activists marched to the beach fence separating Mexico from the United States at the border city of Tijuana chanting, “Trump, we won’t pay for your wall,” then set fire to a crude, besuited effigy of the president on a stick.
