I want to know the answer to the following question:
What senator did Kerry investigate in 1978?
All the background I'm provided with is that "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).". Is that enough to answer the question?
Answer: no
