Sen. John Curtis (R-UT) defended the constitutionality of President Donald Trump cutting funding appropriated by Congress.

The Department of Government Efficiency has identified government contracts, leases, and grants deemed to be wasteful spending and then cut them, sparking legal battles. According to the department, this has already saved $55 billion. Additionally, Trump has paused federal grants via an executive order. Curtis appeared on CBS News’s Face the Nation to suggest that the legal process outlined by the Constitution is “proving to work.”
