Journalists who cover the White House sometimes serve as “pool” reporters. In an effort to limit the number of people involved at any given event, one reporter is designated to report back to other journalists, delivering information that they all can use as if they were present.
That’s what Cheryl Bolen of Bloomberg News did on Saturday. In a report to other White House correspondents, Bolen wrote: “Pooler passes along these comments on background from a source familiar with the president’s health. ‘The president’s vitals over the last 24 hours were very concerning and the next 48 hours will be critical in terms of his care. We’re still not on a clear path to a full recovery.'”
