Explain the specific responsibilities associated with legislative oversight

What will be an ideal response?

An ideal response will:
1, Explain that congressional committees and subcommittees do not leave the scene even after legislation passes; they remain engaged in the process of monitoring the executive branch bureaucracy and its administration of policies, most of which Congress established by passing bills.
2, Explain that committees handle oversight mainly through hearings at which agency heads, cabinet secretaries, and other involved parties testify about their areas.
3, Explain that in the hearings, budgets are reviewed, implementation of new laws is monitored, problems are addressed, and existing policies are refined.
