Last year, the Obamas paid $93K in taxes, and donated $70K-- nearly 15% of their income-- to charity, including Red Cross, United Negro College Fund, and daughters' school.

"President Obama and first lady Michelle Obama reported an adjusted gross income of $477,383 and paid $93,362 in federal taxes for 2014, the White House said Friday. The Obamas' tax documents show they donated $70,712, which is 14.8 percent of their income, to 33 different charities. The largest donation was $22,012 to the Fisher House Foundation, which benefits families of military service members. The family’s effective federal income tax rate was 19.6 percent." -- Jordan Fabian, theHill.com
