Mnuchin, during an appearance on “Fox News Sunday,” argued that the veto tool would give Trump negotiating power over Democrats in case they want more non-defense spending in the next budget.

“I think they should give the president a line-item veto,” said Mnuchin, reiterating comments Trump made last Friday when he signed the omnibus spending bill.

“That was ruled unconstitutional by the Supreme Court,” anchor Chris Wallace reminded Mnuchin.

“Well again, Congress could pass a rule, okay, that allows them to do it,” Mnuchin, a former Goldman Sachs executive, answered.
