Whatever your opinion of Donald Trump, it's impossible to go a full news cycle without hearing the billionaire's name. The New York native's Trump Organization is behind a slew of properties in New York City, Las Vegas, Toronto, Seoul, and other places throughout the world. Then there's Trump the television star, and more recently, Trump the unlikely frontrunner on the Republican ticket.

But what about Trump the philanthropist?

We've written before about Trump's son, Eric, who's only in his early 30s, but whose Eric Trump Foundation, has donated over $28 million to St. Jude Children's Research Hospital in California alone. The Eric Trump Foundation also has a strong web presence.

Donald Trump, meanwhile, has called himself an "ardent philanthropist." Unlike his son's foundation, though, the Donald J. Trump Foundation doesn't have much of a web presence. The foundation has been around since 1987, and according to the most recent tax filings available, gave around $913,000. In 2012, the foundation gave away around $1.7 million. Trump spreads his money around to a number of different outfits, but grants rarely exceed $100,000. It is possible that Trump does much of his giving outside of his formal charitable vehicle, and that more recent gifts—which we can't track—have been larger, but the money coming out of the Donald J. Trump Foundation that we can see is modest compared to Trump's $4 billion net worth.

Of late, Trump has tended to give modest sums to a number of national health organizations such as American Cancer Society, American Diabetes Association, Alliance for Lupus Research, Autism Speaks, Crohn's & Colitis Foundation of America, and more. One particular health cause does not appear to be favored over any other. It is worth noting that in 2011, Trump and his siblings gave a $1 million gift to support and name the Institute for Implant Analysis at the Hospital for Special Surgery, which treated Trump's parents.

Trump has also supported various human services outfits. Last decade, Trump gave at least $1 million to United Way. The foundation has supported Citymeals-on-Wheels and the National Network to End Domestic Violence, among others. Trump also focuses on New York, giving grants to outfits such as New York City Police Foundation, Ronald McDonald House of New York, and New Yorkers For Parks, among others. Trump also gives sums to Florida organizations. The foundation has also given assorted sums to celebrity charities such as the Joe Torre Safe at Home Foundation, which deals with domestic violence.

Trump also recently announced that he was donating $1.1 million of his own personal money to Marine Corps—Law Enforcement Foundation. He also helped net $4.5 million for some two dozen veterans groups including American Hero Adventures in Eugene, Oregon, which provides "stress relieving, and bonding activities to the combat wounded... and their families"; Navy Seal Foundation; and Veterans Airlift Command.

At times, Trump's philanthropy has been contradictory—he supports Gay Men's Health Crisis on the one hand, and the Billy Graham Evangelistic Association, which has decried the influence of the "gay lobby," on the other.
