The main purpose of this legislation is to enhance oversight and accountability of the Congressional Budget Office (CBO) by requiring its Director to testify at annual hearings held by the Budget Committees of both the House of Representatives and the Senate. This aims to ensure that Congress has a clearer understanding of the CBO's budget projections and analyses. Key provisions of the legislation include a mandate for the CBO Director to provide testimony at two hearings each year, as requested by the chair of either Budget Committee.
