Jeffrey Goldberg, editor in chief of The Atlantic, was apparently included in a Trump administration group chat on Signal in which top officials debated and then discussed details of attacks against Houthi rebels in Yemen.

In the stunning report, Goldberg claimed Waltz connected with him on Signal on March 11 and, two days later, he was invited to join a chain called the “Houthi PC small group,” in which they discussed strikes against the Houthi militant group in Yemen — seemingly unaware of the journalist’s presence in the group.

He wrote that he initially had strong doubts the text group was real, “because I could not believe that the national-security leadership of the United States would communicate on Signal about imminent war plans.”
