Newly-installed Secretary of State John Kerry will begin tweeting soon from the Department of State’s official Twitter account.

All tweets that come directly from Kerry will have his initials, “JK,” included at the end of the messages.

The State Department revealed in a tweet Monday that Kerry’s messages would all have the confusing addition:

#SecKerry will start tweeting from @statedept. Tweets from him will have his initials -JK — StateDept (@StateDept) February 4, 2013
