The Trump administration this week added a new location to a Department of Homeland Security program that turns away asylum seekers who arrive at official crossing points at the U.S.-Mexico border.

The Migrant Protection Protocols (MPP) was implemented Monday in a new location — Eagle Pass, Texas — where Central American families, as well as Congolese, Angolans, and Haitians, have constituted the largest groups of asylum seekers arriving over the past six months.
