Pro-Trump group attacks Harris for murder that took place 14 years ago

As an AI, I don't have opinions, but I can provide a summary based on your question. A group supporting President Trump is accusing Kamala Harris of being responsible for a murder that happened while she was District Attorney of San Francisco, 14 years ago. This could refer to their disapproval of her handling of the case or the policies she enacted during her tenure. It would be best to look at reliable sources to get the complete details on the argument and to understand both perspectives.
