Marcus was a top donor to President Trump's 2016 presidential campaign, donating $7 million to help get him elected. He plans to support Trump during the 2020 election as well. He told the Atlanta Journal Constitution that he believes Trump has produced more than any other president and that the U.S. is better off today than it was six or eight years ago.

Just how much Marcus will end up donating depends on Home Depot's success. He still has a large number of shares of stock of the store he co-founded.
