Graduating midshipmen of the U.S. Naval Academy in Annapolis are being told in writing to leave at home or in their vehicles all "ceremonial swords" and anything else "that might be considered a weapon or a threat by screeners" for Friday's outdoor commencement ceremonies featuring an address by President Barack Obama.

Inside the Beltway has obtained the academy's list of prohibited items for this year's graduation exercises, which, besides ceremonial swords, includes umbrellas.
