Helping to make America great again has become this retired Home Depot co-founder’s own DIY project.

Billionaire Bernie Marcus recently made headlines by sharing that he plans to give 80% to 90% of his wealth (estimated at $4.53 billion by Bloomberg, or $5.8 billion by Forbes) to charity when he dies. But the former Home Depot HD, +0.81% chairman also revealed in the same Atlanta Journal-Constitution interview that he will be donating to Donald Trump’s 2020 re-election campaign, as well. Indeed, he donated $7 million to help elect Trump in 2016, according to the Center for Responsive Politics.
