A Mexican national has pleaded guilty to unlawfully reentering the United States after being previously removed multiple times, according to the U.S. Attorney’s Office for the Eastern District of Oklahoma.
Augustin Borja-Gaona, also known by several aliases including Augustine Borja and Genaro Borja-Reynoso, admitted to one count of Unlawful Reentry of Removed Alien. The offense carries a maximum penalty of ten years in prison and a fine up to $250,000.
The case resulted from an investigation conducted by the U.S. Department of Homeland Security’s Immigration and Customs Enforcement Division and the Pittsburg County Sheriff’s Office. Authorities alleged that Borja-Gaona had been removed from the United States in 1999, 2002, 2007, and 2012. He was found again in Oklahoma on March 19, 2025, without permission from federal authorities to return.
“This case is part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations (TCOs), and protect our communities from the perpetrators of violent crime. Operation Take Back America streamlines efforts and resources from the Department’s Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhood (PSN).”
U.S. Magistrate Judge Gerald L. Jackson accepted Borja-Gaona’s plea and ordered a presentence investigation report. Sentencing will be determined by a U.S. District Court Judge after reviewing federal guidelines and statutory factors.
Borja-Gaona remains in custody with the United States Marshals Service until sentencing. Assistant U.S. Attorney Dak T. Cohen prosecuted the case.
