Question: In January 1977, Droney promoted him to First Assistant District Attorney, essentially making Kerry his campaign and media surrogate because Droney was afflicted with amyotrophic lateral sclerosis (ALS, or Lou Gehrig's Disease). As First Assistant, Kerry tried cases, which included winning convictions in a high-profile rape case and a murder. He also played a role in administering the office, including initiating the creation of special white-collar and organized crime units, creating programs to address the problems of rape and other crime victims and witnesses, and managing trial calendars to reflect case priorities. It was in this role in 1978 that Kerry announced an investigation into possible criminal charges against then Senator Edward Brooke, regarding "misstatements" in his first divorce trial. The inquiry ended with no charges being brought after investigators and prosecutors determined that Brooke's misstatements were pertinent to the case, but were not material enough to have affected the outcome.
Is there an answer to this question: Why was Brooke being investigated?

Answer: "misstatements" in his first divorce trial
