Alaska's junior US Senator says President Donald Trump will need the approval of Congress if he wants to strike North Korea pre-emptively.
In national media interviews, Senator Dan Sullivan said Congress holds final authority when it comes to preemptive war strikes.
"Article I of the U.S. Constitution is very clear about that", Sullivan noted.
He said if North Korea should strike first, then the president would have options for military action that wouldn't involve Congressional approval.
Sullivan walked a fine line in online statements today, praising President Trump and his administration for working with Congress so far, but also standing up for embattled Senate Majority Leader Mitch McConnell, whom Trump has criticized heavily in recent days.
