Story highlights Royce said people shouldn't take too much comfort in the failed missile test

Another House Republican said she didn't know Trump's North Korea strategy

"We shouldn't take too much comfort, because even in failure, this program continues to advance," Rep. Ed Royce said on CNN's "State of the Union" with Jake Tapper.
