Last week, after Spicer became aware that information had leaked out of a planning meeting with about a dozen of his communications staffers, he reconvened the group in his office to express his frustration over the number of private conversations and meetings that were showing up in unflattering news stories, according to sources in the room.

Upon entering Spicer’s office for what one person briefed on the gathering described as “an emergency meeting,” staffers were told to dump their phones on a table for a “phone check,” to prove they had nothing to hide.

Spicer, who consulted with White House counsel Don McGahn before calling the meeting, was accompanied by White House lawyers in the room, according to multiple sources. …

The phone checks included whatever electronics staffers were carrying when they were summoned to the unexpected follow-up meeting, including government-issued and personal cellphones.Spicer also warned the group of more problems if news of the phone checks and the meeting about leaks was leaked to the media.
