"We have important insights to share, and we want to make sure that unclassified information about the Agency is more accessible to the American public that we serve, consistent with our national security mission."
The Agency said that in addition to posting "the latest news, statements, and career information from CIA, the Agency's social media updates will also feature artifacts and other information from the CIA's Museum – the best museum most people never get to see."
Within an hour of the CIA's announcement, the CIA Twitter account had more than 40,000 followers.
"Welcome to Twitter! Can't wait to work with you on [REDACTED] :-)" the Twitter account for the National Geospatial-Intelligence Agency said, before retweeting the CIA's tweet.
