Is there any website/service that allows US citizens to sign and send a pre-written letter to their congressman to address this issue, specifically pertaining to the Zika Virus and/or killing mosquitoes? Change.org campaign?

My wife is pregnant now, we live in Southern California, and I feel fairly powerless to do anything except ask my wife to DEET up, be on the lookout for freestanding water, add screens, and pray.
