The conspiracy theory that the Kennedy brothers, John F. Kennedy and Robert Kennedy, were involved in the death of actress Marilyn Monroe is a longstanding and controversial claim. Marilyn Monroe died on August 5, 1962, of a drug overdose. Her death was declared as a suicide; however, some conspiracy theorists have claimed that Monroe was actually murdered and that the Kennedy’s planned it.

One of the key pieces of evidence cited by conspiracy theorists is the fact that Monroe had reportedly had outside affairs with both of the Kennedy brothers.  Some other conspiracy theorists believe that Monroe may have threatened to go public with information about her relationships with the Kennedy brothers and that they arranged for her to be killed to prevent this from happening. Another theory is that the Kennedy’s were worried about Monroe going public and damaging the political career of JFK. This theory is that her death was made to look like a suicide, but it was actually a murder orchestrated by the Kennedy’s or their associates.

There is no concrete evidence to support these claims. While it is true that Monroe had some sort of relationship with both Kennedy brothers there is no credible evidence to show that they were involved in her death or that her death was not a suicide. It is important to note that the death of Marilyn Monroe has been the subject of many conspiracy theories and speculations, but until today, there isn’t any evidence that would support the claim that the Kennedy’s were involved in her death.
