Pence is asked if he agrees with Trump& #39;s understanding of federalism, specifically that his power is "total" here. Pence says, "I support the president& #39;s leadership under the national emergency declaration that he signed."

Pence then adds when pressed: "Make no mistake about it," in this country& #39;s long history, the president& #39;s powers in an emergency are "unquestionably plenary."
