Budgetary Quid Pro Quo Act This bill generally prohibits Congress from considering legislation that authorizes appropriations for a program unless the legislation also includes a provision that reduces an authorization of appropriations for the program or another program by at least the same amount. The bill also requires the Government Publishing Office to establish and maintain an online portal through which members of the public may access information about authorizations of appropriations, including (1) specified details about laws enacted during a Congress that authorize appropriations, and (2) a statement of the total amount of funds authorized to be appropriated during a Congress.
