The leaked NSA Inspector General report detailing the history of the domestic spying program reveals that the authorization allowed NSA to spy on four types of data: "1) telephony content, 2) Internet content, 3) telephony metadata, 4) Internet metadata." According to the NSA it—wrongly—thought the authorization allowed for the collection of solely domestic US communications. The NSA "retain[ed], process[ed], analyze[d], and disseminate[d] intelligence from the" four types of data."
