Given Mitt Romney has yet to publicly disclose his full tax returns (he says he might in April), it's not exactly known what his charitable donations have been. But a new report by ABC says his family charity, the Tyler Foundation, gave $600,000 to the Church of Jesus Christ of Latter-day Saints in 2009.

That's some heavy tithing.

And if that's 10 percent (the suggested giving amount in the Christian Bible) of Romney's income for 2009, he made $6 million that year.

In the past give years, Romney's charity has donated a total $4 million to the church, according to the report.
