USO Supporter,

I was once approached by two service members who recognized me from "That '70s Show." They told me how much the show helped them relax during a difficult deployment to the Middle East. I was so moved by their story that I started looking for more ways to support the members of our military, leading me to participate in 12 USO tours since 2007.

Today, I'm asking you to join me in thanking our heroes ahead of the Army's 250th birthday on Saturday: Will you help me show support for our nation's Army today by adding your name to the USO's Army birthday card?

I've met thousands of service members in the Army and other military branches since then, and it's only made me gain more respect for the heroes who serve. Their bravery, their selflessness, their sacrifices... everything they do is humbling and inspires me to do more.

That's why I'm now in my fourth year of serving as a USO Global Ambassador, proudly advocating for the USO's important mission however I can. But now, I need your help:

I know firsthand how much it means to members of our military when they know they have our support. That's why I've set a personal goal to help the USO collect 50,000 signatures from military supporters like you to help celebrate our Army's 250th birthday. But right now, I'm still very short of my goal and only have a few days to reach it. Will you please join me in signing the card now?

Sign the USO's Army birthday card now to help show our service members in the Army and other branches serving on active duty around the world that they have the support and gratitude of Americans back home.

Thank you for joining me in supporting our nation's heroes.
