JFK Files: Three things we learned

2800 classified files associated with the assassination of John F Kennedy were released by the US. The documents have been unavailable to the public for 25 years. New information available includes a local British paper received a tip off about 'some big news' in America 25 minutes before Kennedy's death. The CIA also suspected Lee Harvey Oswald of being a KGB agent as he had contact with the Russian secret service before and after Kennedy's death. Meanwhile President Donald Trump has blocked the release of around 300 files stating in a memo 'I have no choice.'
