An e-mail is circulating which contends that President Obama has approved a new stamp which celebrates a Muslim holiday. While the stamp exists, it was approved during the reign of his predecessor, not by President Obama, and it was released as part of a series by the U.S. Postal Service, not by some vaguely ominous presidential order. This is clearly an attempt to imply that the president has Muslim sympathies, and no doubt comes from the same crowd who always refer to him as Barack Hussein Obama.
The stamp in question is the EID postage stamp, which was released on September 1, 2001 as part of the USPS Holiday Celebrations Series. It has nothing to do with Christmas, but commemorates the two most important celebrations on the Islamic calendar: Eid Al-Fitr and Eid Al-Adha. Needless to say, President Obama had nothing to do with a stamp that was released by the U.S. Postal Service in 2001.
