President Obama and first lady Michelle Obama had a combined income of $789,674 in 2011 but paid a lower tax rate than the president's secretary, who made less than $100,000, the White House confirmed Friday. The Obamas paid an effective rate of 20.5 percent. White House aides would not reveal presidential secretary Anita Breckenridge’s tax rate but confirmed it was higher than the first family's rate. Breckenridge earned $95,000 last year. The Obamas' rate is less than the 30 percent the president wants millionaires to pay under his proposed Buffett Rule.
