Impending U.S. debt default threatens national security.

The US Treasury Department has warned that it expects to be able to pay the US government's bills only through June 1 without a debt limit increase, leaving just 10 days for White House negotiators and congressional Republicans to reach a deal. Treasury Secretary Janet Yellen said it was "highly likely" that the agency will be unable to meet all US government payment obligations by early June, and as early as June 1, without congressional action to raise the $31.4tn debt ceiling, which would trigger the first-ever US default.
