^Anderson (1997), p.417 (1959)(quote)On April 21, after giving a talk at Princeton, Fidel agreed to a meeting with a CIA official who had asked Lopez Fresquet to act as go-between. They spoke in private for over three hours. The CIA man, Garry Drecher, a German-American emigre who used the alias of "Frank Bender," told Lopez Fresquet afterward that he was convinced Castro was an "anti-Communist" and that they had agreed to exchange information about Communist activities in Cuba.(endquote)
