Trump made the extraordinary announcement on the policy section of his presidential campaign website, Agenda47. In a video, Trump says that the president has "the Constitutional power to stop unnecessary spending through what is known as Impoundment." According to Trump, if Congress appropriates money that he decides is unnecessary, he has the authority to "refuse to waste the extra funds."

Trump . . . has decided that the Impoundment Control Act is unconstitutional and has pledged to challenge it in court. Trump says he will use his self-proclaimed impoundment authority on "Day One" and order "federal agencies to identify portions of their budgets where massive savings are possible through the Impoundment Power." Trump says he will use impoundment to "crush the Deep State."

In his statement, Trump claims that "[l]eading constitutional scholars agree that impoundment is an inherent power of the president." None of those scholars are named.
