After an internal investigation, The White House has settled on an explanation for how 'Signalgate' happened.
National Security Advisor, Mike Waltz, mistakenly saved Jeffrey Goldberg's number in his iPhone under a contact card for Brian Hughes.
The explanation reveals a level of grim stupidity, but it doesn't change the fact that sensitive planning occurred on an encrypted messaging app without Congressional oversight.
Despite the incident, the Trump administration continues to use Signal for its security and instantaneous communication.
