Question: Which is the oldest NFL team that Horton coached with? Passage 1:Businessman Clay Shaw, head of the International Trade Mart in New Orleans, represented the United States on the board of directors for Permindex. On March 1, 1967, Shaw was arrested and charged with conspiring to assassinate President John F. Kennedy by New Orleans District Attorney Jim Garrison. Three days later on March 4, the Italian left-wing newspaper Paese Sera published a story alleging that Shaw was linked to the CIA through his involvement in the Centro Mondiale Commerciale, a subsidiary of Permindex in which Shaw was also said to be a board member. According to Paese Sera, the CMC had been a front organization developed by the CIA for transferring funds to Italy for "illegal political-espionage activities" and had attempted to depose French President Charles de Gaulle in the early 1960s. On March 6, the newspaper printed other allegations about individuals it said were connected to Permindex, including Louis Bloomfield whom it described as "an American agent who now plays the role of a businessman from Canada (who) established secret ties in Rome with Deputies of the Christian Democrats and neo-Fascist parties." The allegations were retold in various newspapers associated with the Communist parties in Italy (l'Unità), France (L'Humanité), and the Soviet Union (Pravda), as well as leftist papers in Canada and Greece, prior to reaching the American press eight weeks later. American journalist Max Holland stated that Paese Sera's allegations connecting Shaw to the CIA eventually led to Garrison implicating the CIA in a conspiracy to assassinate Kennedy.
 Passage 2:On his three-year-old debut, Fenomeno won a minor race over 200 metres at Tokyo on 29 January, beating the subsequent Tenno Sho (autumn) winner Spielberg into second place. He then stepped up in class for the Yayoi Sho (a trial for the Satsuki Sho) at Nakayama and finished sixth of the fifteen runners behind Cosmo Ozora. On 28 April the colt was moved up in distance for the Grade 2 Aoba Sho over 2400 metres at Tokyo and started the 1.1/1 favourite against sixteen opponents. Ridden by Masayoshi Ebina, who became his regular jockey, he recorded his first important success as he came home two and a half lengths clear of Etendard. The colt was then moved into the highest class to contest the Tokyo Yushun on 27 May in which he started at odds of 13.6/1. He was less fancied than Sunday Racing's other two runners World Ace (the favourite) and Deep Brillante with the best of the other runners appearing to be Gold Ship and Grandezza (Spring Stakes). Coming from well off the pace, Fenomeno produced a strong, sustained run on the outside, but just failed to overhaul Deep Brillante and was beaten a nose in a photo finish.
