Sen. Marco Rubio, R-Fla., voiced concerns Thursday about a Mexican judge’s decision to return Afghanistan war veteran Andrew Tahmooressi to jail for breaking Mexico’s strict gun laws.  

“I am very dismayed by the judicial order to continue detaining Sgt. Andrew Tahmooressi in Mexico,” Rubio said. “Sgt. Tahmooressi has been languishing in a Mexican prison long enough.”  

Tahmooressi is from South Florida, according to Rubio’s office.  

“My office met with Sgt. Tahmooressi’s mother in Florida last week and has been in contact with the family from the start of this ordeal,” Rubio continued. “We remain committed to doing whatever we can to assist them during this difficult time.”  

Rubio also called on action from President Barack Obama to help secure Tahmooressi’s release. “It’s time for the Obama administration to wake up and advocate for his return home,” Rubio said. “The Obama administration’s virtual silence and inaction on Sgt. Tahmooressi’s case has been beyond troubling. It’s sheer indifference. The Obama administration needs to step up our diplomatic efforts to bring this Marine home.”  

Tahmooressi says he accidentally drove into Tijuana, Mexico from San Ysidro, Calif., in early April. At the time, he was in possession of three U.S.-registered firearms and was arrested by Mexican officials and jailed on weapons charges.  

Tahmooressi, who served two tours of duty in Afghanistan, had been in the area to receive treatment for post-traumatic stress disorder, according to reports.
