A group of advocacy groups are attempting to turn net neutrality into an election issue ahead of the midterms later this year.

The American Civil Liberties Union (ACLU), CREDO Action, Demand Progress, Fight for the Future, and the Free Press Action Fund are sending a questionnaire to incumbents in the House of Representatives and their challengers, demanding answers on Congress’ effort to overturn the Federal Communications Commission‘s (FCC) decision to rescind net neutrality rules last year.

Congress is attempting to use the Congressional Review Act (CRA), a mechanism that allows lawmakers to overturn federal agency decisions within a certain time frame. The Senate passed its CRA earlier this summer, and the House is currently trying to drum up enough support to pass its own version. The CRA would need just a simple majority to pass. Currently, 177 lawmakers have voiced support for it, making it 41 votes shy of a majority.
