Nearly 135,000 people have signed a petition demanding the release of Marine Corps Sgt. Andrew Tahmooressi from a Mexico prison, prompting an official response from the White House and a rebuke from the reservist’s mother.

“The U.S. State Department continues to provide extensive consular assistance to Mr. Tahmooressi,” stated the official White House response. “We continue to urge the Mexican Authorities to process this case expeditiously.”

Is the U.S. government doing enough to free Marine Corps Sgt. Andrew Tahmooressi?

During an interview on Fox News, Jill Tahmooressi, the mother of the Afghanistan war veteran, expressed her doubts this was true.

“Its been six months,” Jill Tahmorressi said. “Andrew’s case is not being expeditiously processed.”

In March, Andrew Tahmooressi was arrested after he took what he called an accidental wrong turn and crossed into Mexico. Mexican officials arrested him after finding three firearms in his truck. If convicted, he could face up to 14 years in prison for violating Mexico’s gun laws.
