"There's an opportunity, there's a way to use background sourcing to be able to have a much more robust discussion about some things," Spicer said, according to the audio recording. "There's a big difference between (that and) making serious allegations, us coming back on the record and reporters saying 'well we have five sources that are unnamed that say contrary to that.' There's a point at which, there's an obligation if you're going to make a very, very serious allegation, and we're willing to push back on the record, that there be somebody at the very least that's willing to push back on this, and say that they'll put their name attached to it."
