Ironically, the administration would deliver the proposal under authorities and procedures outlined in the Congressional Budget and Impoundment Control Act of 1974 — the same law the administration has flouted for months while illegally withholding, or impounding, funds appropriated by Congress.

But even with that lowered hurdle, the Trump administration is struggling to find much among its unlawful freezing of funds that at least 50 Republican senators are willing to publicly support.
