Article I establishes Congress's power to subpoena witnesses and demand documents in legislative investigations. The Supreme Court confirmed this authority in McGrain v. Daugherty (1927), finding it constitutionally implied—Congress cannot write effective laws without investigating how existing laws work and where problems exist.
Subpoena authority is controlled by committee chairs, which means the majority party effectively controls the investigative tool. Failure to comply with a congressional subpoena can result in a contempt citation and criminal referral to the Justice Department, though enforcement is inconsistent. Presidents have claimed executive privilege to shield certain documents and advisors from subpoenas, creating ongoing battles between branches over investigative scope.
Congressional subpoena power is Congress's main tool for holding the executive branch accountable. Without it, Congress couldn't force officials to testify or hand over documents, making oversight impossible.
People often think congressional subpoenas are the same as criminal subpoenas. In practice, Congress subpoenas to investigate and gather information for legislation; courts subpoena for trials and criminal cases.
