Bill > HRes3

This resolution authorizes the Speaker of the House of Representatives to appoint a two-member committee that will join with a similar committee from the Senate to formally notify the President of the United States that Congress has assembled and is prepared to receive any communications the President wishes to share. This is a traditional procedural step that occurs at the beginning of a new congressional session, serving as a formal constitutional courtesy to inform the President that the legislative branch is convened and ready to conduct its business. The resolution follows standard parliamentary protocol by having the Clerk attest to the document, which provides an official record of the notification process.
