Trump declares border emergency and scraps asylum app in immigration crackdown | 20 Jan 2025 | From behind his desk in the Oval Office, President Donald Trump signed a flurry of executive orders and decrees aimed at cracking down on immigration. From an order tackling the definition of birthright citizenship, to an order declaring the illegal immigration at the border a national emergency, Trump swiftly made moves on his promises to tighten the U.S.-Mexico border. Trump had previously vowed that the "destructive" policies of the Biden White House would be gone "within five minutes." Hours earlier, thousands of would-be migrants had their immigration appointments cancelled after the new administration scrapped CBP One, an app used to book appearances at ports of entry at the border.
