Zoe Lofgren is my Congresswoman. Her office is across the street from where I live. I think I'll visit her office tomorrow to thank her for this; it makes me proud.
Before you do, make sure you spend some time reading the analysis here and on reddit, and come to a solid conclusion whether this proposed change actually would have helped Aaron, or whether it's a feel good attempt to use his name for political gain.
If you have any analyses you think are particularly valuable, feel free to recommend; I'm reading dozens of things per day about this story as it is, at the moment, as so many of us are.
