suspending the debt limit both postpone when Congress
must act on debt limit legislation. The authority for using
such “extraordinary measures,” which include suspensions
and delays of some debt sales and auctions,
underinvestment and disinvestment of certain government
funds, and exchange of debt securities for debt not subject
