Who would I address this petition to?

I want to get a petition started that aims to increase funding to public schools for music education. I am in the D.C. area. To my knowledge, D.C. only has a Delegate to Congress who is unable to vote. So, it seems like it wouldn’t make much sense to address the petition to her.

Should I try writing to a congressman in Maryland or Virginia?
Is there someone else that I haven’t considered?
