The plural form of subpoena is subpoenas.
Subpoenas allow legislators access to documents and personal affects they would not otherwise be able to access. These things can give them more of a sense of the person in for a hearing.
Both the Senate and the House of Representatives have the power to issue subpoenas. This authority allows them to compel witnesses to testify and produce documents as part of their investigative and oversight functions. However, the process and context in which subpoenas are issued may vary between the two chambers. Ultimately, each chamber can enforce its own subpoenas through its respective procedures.
Subpoenas are intended to compel the production of documents and/or live testimony.

Not all congressional committees have subpoena power. While most committees in both the House and Senate can issue subpoenas as part of their oversight and investigative functions, specific authorization is often necessary for certain types of subpoenas. Additionally, the ability to enforce subpoenas may vary depending on the committee's jurisdiction and the context of the investigation. Ultimately, the use of subpoena power is guided by congressional rules and procedures.
