What congressional investigative powers are similar to those in court?

Congressional investigative powers, similar to those in court, include the ability to subpoena witnesses and documents, compel testimony, and administer oaths. These powers allow Congress to gather evidence and conduct inquiries into matters of public interest, such as potential misconduct or violations of law. Additionally, Congress can hold hearings where individuals can be questioned under penalty of perjury, mirroring certain judicial procedures. However, unlike courts, Congress's investigations are primarily aimed at oversight and legislative functions rather than adjudicating disputes.
