104-10107-10122: In 1969, when "Mike" was subpoenaed, he immediately was concerned about "Letizia and his daughter Pat".
Nov. 1961 - Mike wrote first report on Itkin - first "substantive report" in Feb. 1963.
5/15/63 FBI memo: At this time, Brod was described as a CIA contract agent answering directly to James Angleton. Brod was recruited in Italy by JA in 1944. Ray Rocca prepared a full book on Brod and Itkin but they were referred to in it by pseudo. (Note: This is probably the Mike-Portio-Haiti file, referred to in 104-10303-10000, page 10).
9/25/68 memo by CIA assistant general counsel John Greaney: Mike explained to him the relationship between Itkin and CIA and that both he and Itkin worked for CIA. Greaney explained to the District Attorney in NY that Itkin was an unpaid informant, and that such a relationship is not unusual. See 104-10107-10164, Itkin's reports were made to "Mario Brod, who did not use his own name but identified the reports by pseudonym".
5/26/69 memo by C/CI/R&A Ray Rocca: When Mike was subpoenaed in one of Itkin's trials, he immediately was concerned about "Letizia and his daughter Pat".
This 1970 Village Voice article refers to Mario Brod's wife as Letizia.
4/14/70 Deputy Chief, CI Staff, Ray Rocca memo: In a trial where Itkin will be the prime witness, the code name was "Portio".
11/3/70 memo by CIA general counsel Lawrence Houston, looking for "legitimate business for (Brod) outside the jurisdiction during at least this period of time" so that Brod would be unavailable to testify for the defense in a criminal trial, after Brod had appeared in court and been introduced to the judge as a possible witness.
11/23/76: CIA officer Charles A. Briggs reports on the review and destruction of many of Angleton's files - page 10 refers to an Itkin file as well as the Mike-Portio-Haiti file? As "Mike" was Brod, this is another indication that "Portio" was Itkin. Angleton's personal Itkin and Portio files were kept apart from the CIA records system, and were only discovered after Angleton was fired in 1974.
