The FBI had a 270-page file on the late Aretha Franklin after spying on her for 40 years.
The Queen of Soul - who died of cancer in August 2018, aged 76 - was reportedly the target of surveillance, subjected to false phone calls and had her inner-circle infiltrated by spies, according to documents obtained by Rolling Stone from the organisation.
According to the outlet, the lengthy file - which is heavily redacted - is filled with phrases such as "Black extremists", "pro-communist", "hate America", "radical", "racial violence", and "militant Black power" and was filled with suspicion about the singer, her work, and the activists and entertainers she spent time with.
The FBI regularly tracked the Respect singer's addresses and phone numbers and seemed to be particularly interested in her civil rights work and association with the likes of Martin Luther King Jr and Angela Davis.
Among the documents obtained by the publication - some of which are newly-declassified - is a 1968 report on the funeral plans for Martin Luther King Jr, which described it as a "racial situation".
