The National Security Agency sent a bulletin in February warning of Russian hackers trying to access encrypted conversations on Signal.

Such a perceived vulnerability puts the White House in an even worse light after yesterday’s news when Jeffrey Goldberg, an editor at The Atlantic, let it be known that he was accidentally invited to join a chat in which top government officials discussed war plans against Yemen’s Houthis and riled up Europe with some choice words.

Before this week’s report that top Trump officials had mistakenly added a journalist to a group chat on the private messaging app Signal, the National Security Agency had warned of the app’s vulnerabilities despite its claim of being encrypted.
