The organizers of the Democratic National Convention apologized on Wednesday for accidentally using an image of Soviet-era Russian warships in its backdrop during a tribute to veterans at last week's convention in Charlotte, N.C. The ships were shown on a screen behind 50 veterans assembled onstage Sept. 6 during a presentation by retired Adm. John Nathman. "Due to vendor error, incorrect images appeared briefly on screen behind fifty-one veterans during the convention and the DNCC apologizes for this mistake," a Democratic National Convention Committee spokeswoman said in a statement to the Navy Times.
