Staff Sergeant Travis Mills, who lost all four limbs to an IED during his third deployment to Afghanistan in 2012, joined Jenna Lee on "Happening Now" today to give an update on his inspiring story.

Mills, who is one of only five quadruple amputees from the wars in Iraq and Afghanistan, hasn't let his injuries keep him down, as he's gone on to be a motivational speaker, the subject of a documentary film and the author of a best-selling book.

Mills is also helping his fellow wounded warriors and their families through the Travis Mills Foundation, a nonprofit organization.

Through the foundation, he's transforming a property in Rome, Maine, into a special retreat for wounded veterans and their families.

The retreat, which is scheduled to open in several weeks, is a uniquely designed, fully accessible lodge for relaxation, adaptive sports and family recreation.

"We decided to have people come up to Maine, where I live at, and give them a free week with them and their families to do anything they want outdoors and really have a network of people out there to let them know: Never give up and never quit," Mills explained.

He said they will be hosting dozens of families from across the country over the course of seven weeks.

"This facility is all about the veterans and giving back," Mills said.

He also revealed that he is considering entering a new field to help give back even more: politics.

"I could run for some local things and try to help give back to the community," he explained.
