Per the Intercept,
Democrats on the House Intelligence Committee—a GOP-controlled body which just finished its rubber-stamp investigation of Russian interference in the 2016 elections—
released a letter this week outlining steps they would take to investigate whether White House officials are trying to avoid scrutiny via non-official communications channels. They specifically targeted Kushner,
saying if they took control of the House during the upcoming 2018 midterms, they would seek to compel the release of “all messaging applications that Mr. Kushner used during the campaign as well as the presidential transition, including but not limited to SMS, iMessage, Whatsapp, Facebook Messenger, Signal, Slack, Instagram, and Snapchat.”
Later in the letter, the Democrats issued a now-familiar
call for services including Apple and Facebook subsidiary WhatsApp to provide user records for encrypted chat services for persons of interest to the investigation. In the case of Apple, they said they would seek records “reflecting downloaded encrypted messaging apps for certain key individuals,” and they added they
would subpoena WhatsApp “for messages exchanged between key witnesses of interest.” (WhatsApp makes heavy use of end-to-end encryption, meaning the company cannot simply furnish the chat logs, though it does hand over
extensive metadata to authorities upon request.)
