From Mitt's 2010 return, he had nearly $3 million in charitable contributions. Approximately $1.5 million was cash contributions to the Mormon Church and approximately $1.5 million was stock contributions to a foundation called the Tyler Foundation. The Tyler Foundation appears to be the Romney's family foundation. In 2010, the foundation made a $145,000 grant to the Mormon Church and the following other grants (I have no idea what some of these organizations do, but they are all public charities):
The Belmont Hill School ($5,000)
Best Friends Foundation ($15,000)
Boys and Girls Club Of Boston ($10,000)
Brigham Young University ($25,000)
Center For Treatment of Pediatric MS ($75,000)
City Year ($5,000)
Dana Farber Cancer Institute ($10,000)
Dana Farber Pan Mass Challenge ($20,000)
Deseret International ($25,000)
Friends Of The Belmont Council ($20,000)
George W. Bush Library ($100,000)
Harvard Business School ($10,000)
Camp High Hopes ($5,000)
Homes For Our Troops ($20,000)
Inner-City Scholarship Fund ($10,000)
Joey Fund For Cystic Fybrosis ($20,000)
MMOFRA Trom Foundation ($30,000)
MS Cure ($10,000)
Operation Kids ($65,000)
Right To Play ($10,000)
US Equestrian Team Foundation ($10,000)
Wright Museum ($25,000)
I since he didn't deduct all of his contributions in 2011, without really looking through the return, I can't tell how much went to the Mormon Church and how much went to the Tyler Foundation, but those are the only two contributions shown. The Tyler Foundation's Form 990-PF should be available online for 2009 and 2008. Someone else can look and see what grants were made by the foundation in prior years.
This whole thing is stupid. I am a complete partisan hack for the Dems, but for goodness sake, Mitt gives plenty to charity and regardless of your personal views on the Mormon Church, it is a charity that does a lot of good. Most very large charities have investments in things you think they probably shouldn't (shopping malls or whatever) and they pay tax on the income derived from such businesses.
The fact that Mitt gives a ton of money to charity is completely irrelevant to the 47% comment and the fact that his position on most issues would be terrible for the poor.
