Debt Explanation Before Taxwriters Act or the DEBT Act This bill requires the Secretary of the Treasury to appear before the House Ways and Means Committee and the Senate Finance Committee before the federal debt limit is reached or extraordinary measures are taken to prevent the United States from defaulting on its obligations. The term extraordinary measures generally refers to a series of actions that the Department of the Treasury may implement to allow the United States to borrow additional funds without exceeding the debt limit. The measures generally include suspensions or delays of debt sales and suspensions or redemptions of investments in certain government funds. The bill requires the Secretary of the Treasury to appear before the committees to provide a detailed explanation of (1) the extraordinary measures that Treasury will take and the administrative costs of taking the measures, and (2) any reversal of such measures and any other changes in the funding of federal government obligations.
