USO Supporter,

I've been lucky enough to join the USO for several tours and events and meet thousands of our brave service members. It's such an emotional experience each time to listen to their stories and personally thank them for their service and their immense sacrifices.

I know there are many moments in the line of duty where these heroes need a reminder that they are appreciated — when they're facing danger and uncertainty, stationed in unfamiliar places far from home or missing holidays with loved ones.

That's why, this Fourth of July, I hope you'll join me in thanking our service members: I'm helping the USO collect at least 100,000 signatures on a special July 4th thank-you card to honor our heroes, so please, will you add your name next to mine now to thank the troops sacrificing so much to protect our freedom?

Whether I'm shaking hands with troops on the ground or connecting with them virtually around the world, I know a quick expression of thanks goes a long way to boost their morale and strengthen their resiliency. It's the least we can do, to honor those who volunteer to keep us safe and free back home.

So please, before you go out to celebrate our country with family and friends this Fourth of July, can I count on you to be one of the 100,000 signers via email and text messages to thank all the troops sacrificing so much for us? Sign the card now to honor these courageous heroes.

Thank you so much. Happy Fourth of July!
