Donald Trump supporter Ken Langone, the billionaire Republican co-founder of Home Depot, told CNBC on Election Day it isn't his business if Trump is charitable.
The Republican nominee was slammed by billionaire David Tepper on Monday for not giving money in the wake of some New York–area disasters. Tepper called Trump "the father of lies" after watching Trump's wife, Melania, introduce him as generous at a recent campaign event.
However, Langone said being charitable has no bearing on whether one would make a good president.
"The fact that someone may be very philanthropic doesn't mean that they'll be good at governing the country. They're unrelated," Langone said in an interview with CNBC's "Closing Bell."
"I know why my wife and I support our charities and why we do what we do with our wealth. It's not for me to say what somebody else should do with theirs," he added.
Langone is known for his charitable giving.
