President Trump floated the idea of reviving the line-item veto on Twitter Friday evening, and Treasury Secretary Steven Mnuchin appeared on Fox News 36 hours later to echo the proposal.
The subject at hand was the $1.3 trillion omnibus spending bill Trump signed Friday, a package Mnuchin claimed was excessive only because "the Democrats demanded a massive increase in non-military spending." To trim future bills, he argued, Congress "should give the president a line-item veto."
"But that's been ruled unconstitutional by the Supreme Court, sir," Fox host Chris Wallace interjected. Mnuchin was undeterred. "Well, again, Congress could pass a rule, okay, that allows them to do it," he said. "No," Wallace answered, "no, sir, it would be a constitutional amendment." "Chris, we don't — we don't need to get into a debate in terms of — there's different ways of doing this," the treasury secretary sputtered before moving on.
