A report that Romney was considering CIA Director David Petraeus as his Republican vice presidential pick prompted White House press secretary Jay Carney to issue a warning to be "mindful of your sources," The Hill reported Wednesday.
Carney scoffed at the idea that Romney would consider the retired four-star general or that an Obama donor was the source of the story that appeared on the Drudge Report Web site.
Romney campaign manager Matt Rhodes has promised donors the opportunity to be among the first to meet the vice presidential pick once a selection has been announced.
Last week, the campaign debuted a new smartphone app that promises to push notification of the pick to supporters who want to be the first to know.
