FCC Chairman Tom Wheeler is about to get an earful on net neutrality. He’s testifying at a hearing in front of the House Subcommittee on Communications and Technology tomorrow, and Congress members from both sides of the aisle are asking for constituents to contribute questions at the hearing as well using the hashtag #AskWheeler.

This is an important moment because the FCC is supposed to get its marching orders from Congress. As we all learned in middle school, Congress passes laws (in this case, about television, telephones, radio, wire, satellite or cable services). The FCC (as an independent federal regulatory agency) is tasked to figure out how to translate those laws into practical policies and regulations.

Thus, Congress has an important role to play in the struggle for a neutral Internet. We know that members of the subcommittee are planning to re-write the Communications Act, and we know that letters from Congress members aren’t taken lightly by the FCC in the rulemaking process. That means it’s time to let our elected officials and the FCC know that we will fight to protect the future of our open Internet.

Here are three ways to join the debate and have your voice heard:

Today, tweet your questions for FCC Chairman Wheeler during the Communications and Technology Subcommittee hearing using the hashtag #AskWheeler. Call your representative. Let’s be clear: any rules that allow Internet providers to discriminate against how we access websites would be a disaster for the open Internet. Submit comments in the FCC official rulemaking process. We’ve made it easy with our DearFCC.org public comment tool. It’s time to fill the FCC’s Open Internet docket with our voices and our stories. After all, it’s our Internet.

There are no easy solutions. But the FCC and Congress both want and need to hear from us. So let’s give them what they ask for. Let’s defend our Internet.
