Guatemala's office of the presidency said in a Sunday, July 14, 2019 statement that a meeting between Guatemala's President Jimmy Morales and U.S. President Donald Trump would be rescheduled due to legal appeals aimed at preventing Morales from acceding to Trump's requests to allow migrants, including non-Guatemalans, to remain in Guatemala while they apply for U.S. asylum instead of waiting at the Mexico-U.S. border.
