Just for the record, an American flag should never bear "any mark, insignia, letter, word, figure, design, picture, or drawing of any nature," according to U.S. flag code.

Additionally, U.S. Flag Code-Title 4, Ch. 1, Sec. 3 prohibits the "Use of flag for advertising purposes..."

This isn't the first time that President Obama and American flags have sparked controversy. In fact, his campaign appears to have a real problem understanding U.S. flag code.

TheBlaze previously reported that the Obama campaign left a giant American flag on the ground while they were setting up for an official campaign event at the University of Iowa, a blatant violation of U.S. flag code that states an American flag should never touch the ground.
