The primary responsibility for gathering information, taking testimony, and revising legislation in Congress falls to E. standing committees.
In both the Senate and the House, standing committees have jurisdiction over specific subjects and are where most of the work that sets the congressional agenda takes place. These committees gather information, hold hearings, and revise legislation before sending it to the full chamber for a vote.
