The Justice Department on Friday asked the U.S. Supreme Court to intervene after Texas Gov. Greg Abbott blocked federal Border Patrol agents from carrying out their duties in the border city of Eagle Pass, CNN reports. The filing comes after Texas National Guard troops occupied Eagle Pass’ Shelby Park late Wednesday evening, according to CBS News. The Border Patrol had previously used the park, located near International Bridge 1, which connects to the Mexican city of Piedras Negras, as a station for processing asylum seekers.
