Gpt4 says

The responsibility for spending Kamala Harris' campaign funds and incurring $20 million in debt is attributed to her campaign team. The campaign reportedly spent heavily during the election period, which included significant investments in advertising, travel, and polling[^1][^2]. Additionally, there were claims of financial mismanagement and misleading donors about the campaign's prospects[^3][^4]. The campaign raised substantial funds, reportedly over $1 billion, but still ended in debt[^5][^6].
