There?s this bar in New OrleansAnother revelatory JFK document released in full on Dec. 15 was the transcript of a 1978 interview by the House Select Committee on Assassinations with Orest Pena. According to Pena, a bar owner in New Orleans, Lee Harvey Oswald was a U.S. government agent or informant.How did he know? Because Pena himself was an informant, he said. He had given details to the Warren Commission in July 1964 but, as the new document shows, later revealed much more detail about Warren de Brueys, an FBI agent in New Orleans to whom Pena said he reported.Oswald, he claimed, frequented a breakfast place regularly not only with de Brueys but with agents from U.S. Customs and Immigration in New Orleans. Pena believed Oswald had an office in the same government complex.Pena also testified to the House panel that de Brueys had threatened him if he shared with investigators details of their meetings and training of anti-Castro instigators, and that his FBI handler had transferred to Dallas before the assassination. Pena?s testimony, however, was largely discounted by two government commissions.
