Question: Did Eric O'Neill's employer keep files on Elvis Presley?

full_context: Document 1: Brian Krebs: Brian Krebs (born 1972 in Alabama) is an American journalist and investigative reporter. He is best known for his coverage of profit-seeking cybercriminals. His interest grew after a computer worm locked him out of his own computer in 2001.
Document 2: Federal Bureau of Investigation: Beginning in the 1940s and continuing into the 1970s, the bureau investigated cases of espionage against the United States and its allies. Eight Nazi agents who had planned sabotage operations against American targets were arrested, and six were executed (Ex parte Quirin) under their sentences. Also during this time, a joint US/UK code-breaking effort (the Venona project)—with which the FBI was heavily involved—broke Soviet diplomatic and intelligence communications codes, allowing the US and British governments to read Soviet communications. This effort confirmed the existence of Americans working in the United States for Soviet intelligence. Hoover was administering this project but failed to notify the Central Intelligence Agency (CIA) until 1952. Another notable case is the arrest of Soviet spy Rudolf Abel in 1957. The discovery of Soviet spies operating in the US allowed Hoover to pursue his longstanding obsession with the threat he perceived from the American Left, ranging from Communist Party of the United States of America (CPUSA) union organizers to American liberals.
Document 3: Federal Bureau of Investigation: The FBI has been frequently depicted in popular media since the 1930s. The bureau has participated to varying degrees, which has ranged from direct involvement in the creative process of film or TV series development, to providing consultation on operations and closed cases. A few of the notable portrayals of the FBI on television are the 1993-2002 series The X-Files, which concerned investigations into paranormal phenomena by five fictional Special Agents and the fictional Counter Terrorist Unit (CTU) agency in the TV drama 24, which is patterned after the FBI Counterterrorism Division. The 1991 movie Point Break is based on the true story of an undercover FBI agent who infiltrated a gang of bank robbers. The 1997 movie Donnie Brasco is based on the true story of undercover FBI agent Joseph D. Pistone infiltrating the Mafia.
Document 4: Federal Bureau of Investigation: Between 1993 and 1996, the FBI increased its counter-terrorism role in the wake of the first 1993 World Trade Center bombing in New York City, New York; the 1995 Oklahoma City bombing in Oklahoma City, Oklahoma; and the arrest of the Unabomber in 1996. Technological innovation and the skills of FBI Laboratory analysts helped ensure that the three cases were successfully prosecuted. Justice Department investigations into the FBI's roles in the Ruby Ridge and Waco incidents were found to be obstructed by agents within the Bureau. During the 1996 Summer Olympics in Atlanta, Georgia, the FBI was criticized for its investigation of the Centennial Olympic Park bombing. It has settled a dispute with Richard Jewell, who was a private security guard at the venue, along with some media organizations, in regard to the leaking of his name during the investigation.
Document 5: Federal Bureau of Investigation: The USA PATRIOT Act increased the powers allotted to the FBI, especially in wiretapping and monitoring of Internet activity. One of the most controversial provisions of the act is the so-called sneak and peek provision, granting the FBI powers to search a house while the residents are away, and not requiring them to notify the residents for several weeks afterwards. Under the PATRIOT Act's provisions, the FBI also resumed inquiring into the library records of those who are suspected of terrorism (something it had supposedly not done since the 1970s).
Document 6: Eric O'Neill: Eric Michael O'Neill (born March 3, 1973) is an American former FBI counter-terrorism and counterintelligence operative. He worked and was entitled as an Investigative Specialist with the Special Surveillance Group (SSG) and played a major role in the arrest, conviction, and life imprisonment of FBI agent Robert Hanssen for spying on behalf of the Soviet Union and the Russian Federation. His book written about this experience, Gray Day: My Undercover Mission to Expose America's First Cyber Spy, was published in spring 2019. He is a public speaker and security expert who currently lectures internationally about espionage and national security, cybersecurity, fraud, corporate diligence and defense, hacking, pursuing dreams and surviving Hollywood.
Document 7: Tinker Tailor Soldier Spy: It is 1973, the height of the Cold War. George Smiley, former senior official of Britain's Secret Intelligence Service (known as ``the Circus ''because its London office is at Cambridge Circus), has been living in unhappy retirement for a year after an operation in Czechoslovakia, codenamed Testify, ended in disaster with the capture and torture of agent Jim Prideaux. The failure resulted in the dismissals of Smiley and his superior, Control, the head of the Circus. Smiley is unexpectedly approached by Peter Guillam, his former protege at the Circus, and Under - Secretary Oliver Lacon, the Civil Service officer responsible for overseeing the Circus. At Lacon's home they meet with Ricki Tarr, a Circus agent who had been missing for months and had been declared persona - non-grata upon suspicion of having defected to Moscow. Tarr tells them of the existence of a Soviet mole at the highest level of the Circus. The mole is codenamed Gerald and is handled by Moscow Centre's agent, Polyakov, stationed at the Soviet embassy in London. Tarr tells them that when he obtained this information from a female Russian diplomat visiting Hong Kong and informed London, the woman was forcibly returned to Moscow. Tarr, realising someone in London had betrayed him, went on the run, eventually coming out to contact his former boss Guillam, the only person in the Circus he could trust.
Document 8: Robert Ressler: Robert Kenneth Ressler (February 21, 1937 -- May 5, 2013) was an FBI agent and author. He played a significant role in the psychological profiling of violent offenders in the 1970s and is often credited with coining the term ``serial killer. ''After retiring from the FBI, he authored a number of books on serial murders, and often gave lectures on criminology.
Document 9: Federal Bureau of Investigation: During the 1950s and 1960s, FBI officials became increasingly concerned about the influence of civil rights leaders, whom they believed had communist ties or were unduly influenced by them. In 1956, for example, Hoover sent an open letter denouncing Dr. T.R.M. Howard, a civil rights leader, surgeon, and wealthy entrepreneur in Mississippi who had criticized FBI inaction in solving recent murders of George W. Lee, Emmett Till, and other blacks in the South. The FBI carried out controversial domestic surveillance in an operation it called the COINTELPRO, which was short for "COunter-INTELligence PROgram." It was to investigate and disrupt the activities of dissident political organizations within the United States, including both militant and non-violent organizations. Among its targets was the Southern Christian Leadership Conference, a leading civil rights organization with clergy leadership.
Document 10: Federal Bureau of Investigation: On July 8, 2007 The Washington Post published excerpts from UCLA Professor Amy Zegart's book Spying Blind: The CIA, the FBI, and the Origins of 9/11. The Post reported from Zegart's book that government documents show the CIA and FBI missed 23 potential chances to disrupt the terrorist attacks of September 11, 2001. The primary reasons for the failures included: agency cultures resistant to change and new ideas; inappropriate incentives for promotion; and a lack of cooperation between the FBI, CIA and the rest of the United States Intelligence Community. The book blamed the FBI's decentralized structure, which prevented effective communication and cooperation among different FBI offices. The book suggested that the FBI has not evolved into an effective counter-terrorism or counter-intelligence agency, due in large part to deeply ingrained agency cultural resistance to change. For example, FBI personnel practices continue to treat all staff other than special agents as support staff, classifying intelligence analysts alongside the FBI's auto mechanics and janitors.
Document 11: Federal Bureau of Investigation: In 1939, the Bureau began compiling a custodial detention list with the names of those who would be taken into custody in the event of war with Axis nations. The majority of the names on the list belonged to Issei community leaders, as the FBI investigation built on an existing Naval Intelligence index that had focused on Japanese Americans in Hawaii and the West Coast, but many German and Italian nationals also found their way onto the secret list. Robert Shivers, head of the Honolulu office, obtained permission from Hoover to start detaining those on the list on December 7, 1941, while bombs were still falling over Pearl Harbor. Mass arrests and searches of homes (in most cases conducted without warrants) began a few hours after the attack, and over the next several weeks more than 5,500 Issei men were taken into FBI custody. On February 19, 1942, President Franklin Roosevelt issued Executive Order 9066, authorizing the removal of Japanese Americans from the West Coast. FBI Director Hoover opposed the subsequent mass removal and confinement of Japanese Americans authorized under Executive Order 9066, but Roosevelt prevailed. The vast majority went along with the subsequent exclusion orders, but in a handful of cases where Japanese Americans refused to obey the new military regulations, FBI agents handled their arrests. The Bureau continued surveillance on Japanese Americans throughout the war, conducting background checks on applicants for resettlement outside camp, and entering the camps (usually without the permission of War Relocation Authority officials) and grooming informants in order to monitor dissidents and "troublemakers." After the war, the FBI was assigned to protect returning Japanese Americans from attacks by hostile white communities.
Document 12: Federal Bureau of Investigation: FBI records show that 85% of COINTELPRO resources targeted groups and individuals that the FBI deemed "subversive", including communist and socialist organizations; organizations and individuals associated with the Civil Rights Movement, including Martin Luther King, Jr. and others associated with the Southern Christian Leadership Conference, the National Association for the Advancement of Colored People, and the Congress of Racial Equality and other civil rights organizations; black nationalist groups; the American Indian Movement; a broad range of organizations labeled "New Left", including Students for a Democratic Society and the Weathermen; almost all groups protesting the Vietnam War, as well as individual student demonstrators with no group affiliation; the National Lawyers Guild; organizations and individuals associated with the women's rights movement; nationalist groups such as those seeking independence for Puerto Rico, United Ireland, and Cuban exile movements including Orlando Bosch's Cuban Power and the Cuban Nationalist Movement. The remaining 15% of COINTELPRO resources were expended to marginalize and subvert white hate groups, including the Ku Klux Klan and the National States' Rights Party.
Document 13: Kill or Capture: How a Special Operations Task Force Took Down a Notorious al Qaeda Terrorist: Kill or Capture: How a Special Operations Task Force Took Down a Notorious al Qaeda Terrorist is a book published by Macmillan Publishing in early 2011. The author, a former interrogator, criticizes the use of ""extended interrogation techniques"".
Document 14: Federal Bureau of Investigation: During the September 11, 2001 attacks on the World Trade Center, FBI agent Leonard W. Hatton Jr. was killed during the rescue effort while helping the rescue personnel evacuate the occupants of the South Tower and stayed when it collapsed. Within months after the attacks, FBI Director Robert Mueller, who had been sworn in a week before the attacks, called for a re-engineering of FBI structure and operations. He made countering every federal crime a top priority, including the prevention of terrorism, countering foreign intelligence operations, addressing cyber security threats, other high-tech crimes, protecting civil rights, combating public corruption, organized crime, white-collar crime, and major acts of violent crime.
Document 15: Federal Bureau of Investigation: The FBI has maintained files on numerous people, including celebrities such as Elvis Presley, Frank Sinatra, John Denver, John Lennon, Jane Fonda, Groucho Marx, Charlie Chaplin, the band MC5, Lou Costello, Sonny Bono, Bob Dylan, Michael Jackson, and Mickey Mantle. The files were collected for various reasons. Some of the subjects were investigated for alleged ties to the Communist party (Charlie Chaplin and Groucho Marx), or in connection with antiwar activities during the Vietnam War (John Denver, John Lennon, and Jane Fonda). Numerous celebrity files concern threats or extortion attempts against them (Sonny Bono, John Denver, John Lennon, Elvis Presley, Michael Jackson, Mickey Mantle, Groucho Marx, and Frank Sinatra).
