Most of what the government released tonight is not new -- in fact, much of what has attracted attention on social media and in news reports has long been in the public domain, except for minor redactions, such as the blacking out of personally-identifiable information of CIA sources or employees, including names and addresses, which have now been disclosed.

… Another newly-disclosed portion details CIA surveillance of Soviet embassies in Mexico City and efforts to recruit double agents from Soviet agency personnel -- and reveal the names and positions of those who were recruited.

…[one] memo also details the CIA's surveillance of an American man described as a Communist living in Mexico. The bulk of the memo is a listing of phone numbers that were tapped by the U.S. government.

… Unredacted text of a June 1961 memo on the CIA -- sent to Kennedy by aide Arthur Schlesinger Jr. -- contained harsh criticism of the spy agency just months after its backing of the ill-fated Bay of Pigs invasion.

… One 1964 document showed that two intelligence assets discussed potentially assassinating Castro under the administration of President Lyndon Johnson.

The document said the CIA was allegedly "formerly in favor of such a plan," but it was "shelved" due to the opposition of Attorney General Robert F. Kennedy.

Another previously released document detailed RFK being briefed on potential plans to kill Castro. "RFK asks to be told before the CIA works with the Mafia again," a footnote of the document read.
