	Introduction

The leaders of the eight legislative branch agencies and entities—the Government Accountability Office, the Library of Congress, the Government Publishing Office (formerly Government Printing Office), the Office of the Architect of the Capitol, the U.S. Capitol Police, the Congressional Budget Office, the Congressional Research Service, and the Office of Compliance—are appointed in a variety of manners. The first four agencies are led by a person appointed by the President, with the advice and consent of the Senate. The next two are appointed by Congress, the next by the Librarian of Congress, and the last by a board of directors. Congress has periodically examined the procedures used to appoint legislative branch officers with the aim of protecting the prerogatives of, and ensuring accountability to, Congress within the framework of the advice and consent appointment process established in Article II, Section 2 of the Constitution. The report also briefly addresses legislation considered, but not enacted, in the 115 th Congress to change the appointment process for the Register of Copyrights.
