The rules for the people writing the rules can seem like a black box, and that’s because to an extent they are. Demand Progress has voiced concerns for years that House Republicans are the only conference publishing their rules online (they also post their proposed changes to rules so extra credit for them).
Historically Senate Republicans and Democrats in both chambers haven’t published their conference rules, leaving the public in the dark, until now. House Democratic Caucus rules were recently published, along with the House Republican Conference rules. Now the Senate needs to step their game up and put their rules online as well.
