Title should be corrected to read “Fake News blocked from attending White House gaggle”
"Gaggles" historically refer to informal briefings the press secretary conducts with the press pool rather than the entire press corps....they were more or less off the record, and their purpose was mostly to exchange information - the president's schedule and briefing schedule, from the administration side; heads-up on likely topics or early comment on pressing issues, from the news side....When the President traveled, sometimes the press secretary would hold a gaggle with the press pool that travels on Air Force One - not every time, but sometimes, and always informally."
