NEW YORK — John Mayer is launching a foundation focused on improving the health of veterans through scientific research.

The Grammy-winning singer on Friday announced The Heart and Armor Foundation, which plans to focus on veterans with post-traumatic stress disorder and meeting the emerging needs of women veterans.

Though he publicly announced the foundation on Friday, Mayer has been working on the organization since 2012 alongside veterans, scientists and clinicians.

“We’re going to the public with things like published research papers and having raised enough money to really build some pilot programs. We have some really great data and … we want it to be working first so that a lot of the questions were answered before we brought things to people by way of awareness,” Mayer said in an interview with The Associated Press. “I think it just makes it that much more compelling and much more concise to bring it to people with the message being, ‘Hey, this is not taking something that is zero to try to get it to five. This is something that is at 50 and we want to get it to 100.'”

Mayer, whose father was a World War II veteran, said part of the reason he started The Heart and Armor Foundation came after he visited the Marine Corps Base Camp Lejeune in 2008.
