Twenty minutes later, NBC offered only this sorry retraction:

UPDATE: BuzzFeed reports that Clinton left the hospital for an MRI today. And the Daily Mail has pictures. 

NBC News has not reported via its Twitter feed on the latest development.

UPDATE II: Now NBC News again reports on Twitter that Clinton has left the hospital:

JUST IN: Sec. of State Hillary Clinton released from hospital after completing treatment for blood clot
