1. Administration Defends Plan to Close Border and Stop Aid

2. In an interview on Sunday at ABC Studios in New York, Mick Mulvaney, the acting White House chief of staff, defended President Trump’s threat to end assistance to three Central American countries and to close parts of the United States border with Mexico next week, saying that it would take “something dramatic” to prevent Mr. Trump from carrying out that plan. Critics say the president’s move to cut off aid to Guatemala, Honduras and El Salvador ignores a longstanding strategy touted by aid groups and military experts — including the president’s former chief of staff — that supporting those countries actually makes the border safer. John F. Kelly, the president’s former chief of staff and former top officer of the military’s Southern Command, said during an Atlantic Council meeting that his experience showed him that partnering with Northern Triangle countries was key to securing the border. President Trump argues that point and has focused on how border patrol facilities along the southwestern border have been strained to a breaking point by the largest influx of migrants in years. The president is seeking to punish those countries for what he says is a failure to stop migrant caravans from making their way north. Whiles experts within the president’s own administration have said aid money has helped curb violence in and migration.
