In 2002, President George W. Bush and Congress authorized a Medal of Honor flag to be presented to recipients of the decoration. The flag design was suggested by retired Army Special Forces First Sergeant Bill Kendall of Jefferson, Iowa. Kendall's design of a light blue field emblazoned with 13 white five-pointed stars was the basis of the flag suggested by Sarah LeClerc of the Institute of Heraldry. LeClerc's design, ultimately accepted as the official flag, does not include the words "Medal of Honor" as did Kendall's original design, and is fringed in gold. The color of the field and the 13 white stars, arranged in the form of a three bar chevron, consisting of two chevrons of five stars and one chevron of three stars, replicates the suspension ribbon of the Medal of Honor.
