"The Constitution’s
Article I, Section 9 grants Congress the power of the purse to approve spending in the federal budget in the
Appropriations Clause, which reads in part, “No Money shall be drawn from the Treasury, but in Consequence of Appropriations made by Law.”
The Constitution then delegates to the president the task of spending approved funds in the
Take Care Clause, which requires the chief executive “shall take Care that the Laws be faithfully executed.”
Shortly after President Donald Trump took office, his administration briefly paused federal spending on various programs. Although that spending has been restored, the move led to questions about the separation of powers between the president and Congress.
