Home Depot cofounder Bernie Marcus has a plan for how to spend his $5.9 billion fortune, says Business Insider. Marcus wants 80 to 90% of his fortune to go to various philanthropic causes, but he's also a major political donor. Marcus was one of Donald Trump's largest donors in 2016, giving $7 million to his campaign. Marcus said he planned to financially support the president in the 2020 election as well.
