U.S. to stand with Puerto Rico until "job is done": White House

"This country, our country, will stand with those American citizens in Puerto Rico until the job is done," Kelly told reporters at the White House, adding that the president's tweet on Thursday morning was "exactly accurate."

"They're not going to be there for ever," he said, referring to personnel from the Federal Emergency Management Agency and the U.S. military.
