McALLEN, Texas — Texas is offering a parcel of rural ranchland along the U.S.-Mexico border to use as a staging area for potential mass deportations under President-elect Donald Trump. The property, which Texas originally purchased last month, is located in rural Starr County in the Rio Grande Valley. Republican Dawn Buckingham, the Texas Land Commissioner, sent a letter on Thursday to Trump extending the offer.
