WATCH: Marine Vet Escorted from Clinton Event After Asking About Benghazi

'PAWS Act' Would Provide Wounded Warriors With Service Dogs

Ryan Weldon left Delaware on foot last February, and now he has wound up in San Francisco.

That’s because the Marine Corps veteran has just walked an astonishing 5,000 miles across the country – all in the hopes of raising awareness for PTSD.

For Weldon, a South Carolina native, the 400-day journey started after he got tired of hearing about the high rate of veteran suicides.

“Twenty-two veterans a day take their own life due to post-traumatic stress,” he said. “As a Marine, I refuse to sit by and do nothing.”

Weldon started a GoFundMe page to raise money for the PTSD Survivors of America organization.

Fox 2 reported he then “walked alone across the United States, pushing a cart he called the Freedom Flyer, adorned with an American flag.”

At Northern California's Ocean Beach on Saturday, Weldon’s mom met him at the finish line with a huge hug and tears of joy.

“I can’t even begin to tell you what he’s been through to get here. Harsh weather, freezing cold, blizzards, mountains, bears, coyotes… things a mom does not want to hear about,” she said.

But Weldon said the road to help PTSD survivors has not ended.

“The journey is to get the word out there and let people know how serious it is,” he said.
