Yellen urged to disregard 'unconstitutional' debt limit lawsuit.

A union of government employees has sued Treasury Secretary Janet Yellen and President Joe Biden to try to stop them from complying with the law that limits the government’s total debt, which the lawsuit contends is unconstitutional. The lawsuit argues that if Yellen abides by the debt limit once it becomes binding, possibly next month, she would have to choose which federal obligations to actually pay. Doing so, it contends, would violate the Constitution’s separation of powers. The debt limit, currently $31.4 trillion, was reached in January. But Yellen has since used various accounting measures to avoid breaching it.
