Which concludes that he was there, stayed in the hotel, signed his name.
I believe that Lee Oswald did go to Mexico City......
Let me propose this question.... Would Lee have become irate and angry at FBI agent Hosty for simply asking if he had been to Mexico City, if he had not been there?
Lee knew that there was a connection between his presence in Mexico City, and the assassination. That's why he became angry and adamantly denied that he had been to MC.
