Donald Trump proposed hiring 10,000 additional Border Patrol agents and giving them a $10,000 retention and signing bonus — months after he derailed a bipartisan bill to fund more border personnel. The former president made his pledge during a rally Sunday in Prescott Valley, Arizona, roughly 260 miles north of the state’s border with Mexico. He accepted an endorsement from the agents’ union, the National Border Patrol Council, which is a longtime Trump backer that endorsed him during his prior two campaigns. Trump has made illegal immigration the focus of his campaign. He blames Vice President Kamala Harris, his Democratic opponent, for a record spike in unauthorized crossings at the U.S.-Mexico border.
