It is a really bad day for someone in the Public Affairs Office at the Pentagon after this mishap:
The Pentagon posted an unusual message on Twitter Thursday — one urging President Donald Trump to resign.
Defense Department spokeswoman Dana White said an “authorized operator” of the Pentagon website “erroneously retweeted content that would not be endorsed by the Department of Defense. The operator caught this error and immediately deleted it.” [Yahoo]
You can read more at the link, but my assumption is that the operator likely thought they were logged into their personal Twitter account, but actually logged into the DoD account. Doh!
