The purpose of this legislation is to improve the accuracy and timeliness of budget information provided to Congress. It aims to ensure that the Congressional Budget Office (CBO) regularly updates its budget baseline, which is a key reference point for lawmakers when making financial decisions. One of the main provisions of the legislation requires the CBO to provide at least two updates to its budget baseline each year. These updates must include economic data that the CBO used to make its calculations. Additionally, the CBO is allowed to provide more updates if necessary.
