Janet Yellen announced that the U.S. Treasury will implement extraordinary measures starting January 21, following the inauguration of President Trump, as the nation approaches its debt ceiling. The measures include suspending investments in federal retirement funds to maintain government operations. With the national debt exceeding $36 trillion, Yellen urged Congress to promptly raise the debt ceiling to avoid default. Trump has expressed support for abolishing the debt ceiling altogether, complicating future legislative strategies as Republicans hold control of both the House and Senate.
