In interviews, nearly a dozen White House aides and federal agency staffers described a litany of suspicions: that rival factions in the administration are trying to embarrass them, that civil servants opposed to President Donald Trump are trying to undermine him, and even that a “deep state” of career military and intelligence officials is out to destroy them.

Aides are going to great lengths to protect themselves. They’re turning off work-issued smartphones and putting them in drawers when they arrive home from work out of fear that they could be used to eavesdrop. They’re staying mum in meetings out of concern that their comments could be leaked to the press by foes.

Many are using encrypted apps that automatically delete messages once they’ve been read, or are leaving their personal cell phones at home in case their bosses initiate phone checks of the sort that press secretary Sean Spicer deployed last month to identify leakers on his team…

Some rank-and-file White House aides, meanwhile, have become convinced that intelligence agents may be monitoring their phone calls, emails, and text messages. Those fears intensified last week when WikiLeaks released a trove of CIA documents outlining how the agency can break into phones and computers.
