The former Marine, who sufferers from Post-Traumatic Stress Disorder due to multiple combat tours in Southwest Asia, was heading into Mexico as part of a surfing trip with a fellow Marine Corps veteran when he was arrested.
While incarcerated, Hammar's family reportedly recieved extortion threats by Mexican nationals threatening to kill the Marine Corps veteran.
News of the threats sparked outrage among many on Capitol Hill, with many lawmakers pressing Mexican diplomats to secure Hammar's release.

Ileana Ros-Lehtinen (R-FL), whose district Hammar's family resides in, drafted a letter Thursday to Secretary of State Hillary ClintonHillary Rodham ClintonFormer Clinton spokesman: Virginia elections will begin resistance to Trump Scarborough: Missed opportunities in Trump’s inauguration speech Chelsea Clinton: Let Barron Trump be a kid MORE and Department of Homeland Security chief Janet Napolitano calling for the Marine's release.
House Armed Services Committee member and former Marine Rep. Duncan Hunter (R-Calif.) has called for an immediate travel ban on Mexico until Hammar is returned to the United States.
News of Hammar's release drew praise from Duncan and others, but the California Republican noted the case would not be closed until Hammar is safe within U.S. borders.
“I’m glad better sense prevailed in Mexico and there’s now a plan in place for Jon Hammar’s release," Hunter said in a statement Friday. "It’s unfortunate that Jon and his family had to endure this situation, but the issue is only resolved when he steps foot back on American soil."
