“The Constitution’s text is clear that Congress must authorize appropriations and the president must “take Care” that those laws are “faithfully executed.” There is no basis in constitutional text or history for the president to claim open-ended power to impound funds in the manner of the OMB memo. In 1975, the Supreme Court rejected former President Richard Nixon’s claim to be able to spend less than Congress had appropriated. That ruling would have had to come out the other way if the president had a constitutional power to impound. (Perhaps aware of this reality, OMB issued a later memo claiming the freeze was not, in fact, an “impoundment.” But this is just a semantic sleight of hand: For entities that need federal funds this or next week in particular, there is no meaningful difference.)”

“If anything, the Supreme Court has tightened the constitutional leash on such unilateral claims of executive authority untethered from a statutory anchor. With Justice Neil Gorsuch leading the charge, it has stressed instead the need for clear authority from Congress for the exercise of any delegated power, including the power to write regulations. The OMB memo makes a mockery of those decisions by allowing the president to do with money what now isn’t allowed with regulations.
It is true that there is a scattering of past instances of impoundment. But these isolated cases largely concern foreign affairs and national security matters. In 1803, for example, Thomas Jefferson declined to spend funds for 15 gunboats for fear that they would upend secret talks with a foreign sovereign, Napoleonic France. Whatever unilateral presidential authority exists over foreign affairs cannot constitutionally be spread with reckless abandon to cover any or all domestic spending.
Past presidents have also confronted conflicts between a legislative command and Congress’ failure to appropriate funds to execute that command. There, presidents are forced to make a choice between dueling statutory orders. Courts rarely address these conflicts. But it is striking to note that in a 2012 case involving competing mandates, the Supreme Court rejected the executive’s claim to be able to withhold promised funds.”

“The impoundment power Trump’s White House asserts would drive a stake through Congress’ constitutional authority.
Exactly like the line-item veto invalidated by the Supreme Court in 1998, the claimed impoundment power is de facto power to selectively edit duly enacted laws. This claimed nonenforcement should elicit whiplash among conservatives. After all, it was red states such as Texas, aided by Trump’s adviser Stephen Miller, that once excoriated the Biden administration for negating federal laws on immigration via nonenforcement. (The Biden administration, however, could point to statutory conflicts that don’t exist in this case.)”
