KMBC-TV of Kansas City, Kan., reported that Gill Studios was printing campaign material for a Democratic ticket of Illinois Sen. Barack Obama and Indiana Sen. Evan Bayh.

Bayh is one of several people widely reported to be on Obama's shortlist of vice presidential possibilities -- along with Delaware Sen. Joe Biden, Virginia Gov. Tim Kaine and Kansas Gov. Kathleen Sebelius. News organizations have been trumpeting for days the impending announcement of Obama's choice and the presumptive nominee has said he's decided on a running mate, but his campaign has succeeded so far in keeping the name under wraps.

KMBC said Friday that Gill Studios would neither confirm nor deny it was printing Obama-Bayh material.

"We're very disappointed that you would spread this rumor," Gill Studios President Tom Carrico told the TV station.

Obama has called some of those on his shortlist to tell them they weren't selected, a Democratic Party source said. MSNBC reported Friday that Obama had notified Bayh and Kaine he had not selected them.

Obama is scheduled to attend a rally Saturday in Springfield, Ill., with his choice for vice president.
