Once panels are organized they can begin the work of holding hearings and considering legislative proposals. Reporting Legislation6

At the end of a markup, a chair normally entertains a motion to report a measure favorably to the House. A clean bill would be introduced in the House and referred back to the committee. For example, most reports explain a measure's purpose and the need for the legislation, its cost, committee votes on amendments and the measure itself, the position of the executive branch, and the specific changes the bill would make in existing law. Oversight and Investigations

Committees periodically conduct reviews of agency performance in the implementation of legislation, called oversight, or conduct investigations into perceived wrongdoing, referred to as investigations.
Committees are integral to the work of Congress in determining the policy needs of the nation and acting on them. This report provides a brief overview of six features of the committee system in the House: organization, hearings, markup, reporting, oversight, and publications. Committees in the House have four primary powers: to conduct hearings and investigations, to consider bills and resolutions and amendments to them, to report legislation to the House for its possible consideration, and to monitor executive branch performance, that is, to conduct oversight. The report will be updated as events warrant.
