President Barack Obama delivered his third annual State of the Union speech to a joint session of Congress.

The president renewed his call for his "Buffet Rule" on tax. This is the principle that millionaires should not pay a lower tax rate than typical workers.

The president named his idea after billionaire Warren Buffett, who says it is unfair that his secretary pays a higher tax rate than he does. The White House invited Buffett's secretary, Debbie Bosanek, to attend the speech as a special guest.
