The official inquiry into the kennedy assassination was called

The official inquiry into the Kennedy assassination was called the Warren Commission.

Explanation:

The Presidential Commission on the Assassination of President Kennedy, known as the Warren Commission, was an American presidential commission created by a decree of President Lyndon Johnson of November 29, 1963 to investigate the circumstances of the assassination of President Kennedy.

The Commission took its unofficial name from its President, Earl Warren, then President of the United States Supreme Court.

His final 888-page report was presented to President Johnson on September 24, 1964, and was released three days later. It concluded that Lee Harvey Oswald had acted alone in the assassination of President Kennedy and the injury of Texas Governor John Connally. Since their publication, the conclusions of this report have been controversial: the work of the Commission has been criticized point by point by some subsequent studies and supported by others.
