PIEDRAS NEGRAS, Mexico (Reuters) - Shortly after Donald Trump was sworn in as U.S. president on Monday, Honduran migrant Denia Mendez's phone started buzzing with news that the app she had used to book her U.S. asylum appointment was down.
Afraid of what this meant for her long-awaited appointment on Jan. 21, Mendez, sitting in the patio of a migrant shelter in the Mexican border town of Piedras Negras, called her teenage daughter Sofia who had the CBP One appointment app on her phone.
