The US national debt has surpassed $40 trillion, a significant milestone. This figure was reached just five months after the debt hit $39 trillion in March, and ten months after it reached $38 trillion in October. Defense costs, social programs, and interest on the deficit make up a large share of federal spending.

The $40 trillion figure highlights competing priorities, including defense spending and efforts to lower everyday costs. Further details on the national debt and its implications are available from the source.
