Texas Governor Greg Abbott said Sunday he is expanding his troops' control of the southern US border to protect it from a migrant "invasion," as President Joe Biden's administration accuses him of overstepping his authority.
Abbott, flanked by 13 fellow Republican state governors, arrived at Shelby Park, in the Texan city of Eagle Pass, which has an access ramp to the Rio Grande river that forms the natural boundary between the United States and Mexico.
