Murder makes the intent sound more petty; less important, more personal, and less political than it really is
Assassination indicates political intent and societal effect, and even a sketchy history of skeletons behind the assassinated that led to this

I don't think it matters. Both terms have their strengths. Using the term "assassinated" elevates the victim, which works to justify the unequal allocation of resources for investigation of a rich guy's death.
Also the term "murder" doesn't imply justification, only that you killed someone on purpose.
Murder implies that it was unlawful, which is technically true, but I don't like the idea of ceding that ground.
Assassination isn't lawful either
