Washington (CNN) - For the second time on Tuesday, Vice President Joe Biden briefly commented on the controversial secret tape of a Mitt Romney fundraiser in May.
But in his second remarks on the matter, Biden went further than he had gone earlier: he raised the issue unprompted by reporters, indicated that he was aware of the interest in his reaction and essentially said that more will come, soon, from the Obama campaign.
Biden briefly spoke to reporters on his plane traveling with him back to Washington after a two-day trip to Iowa.
Biden began by thanking the reporters for accompanying him on the trip. He then said, without being asked about the secret tape: "I'm not commenting on Romney."
And yet Biden explained he was aware of reporting on his earlier response to the controversy.
"Somebody filed a story saying, essentially saying, 'Biden hadn't said anything,'" the vice president said. "And he's not going to."
A reporter asked Biden: why not.
"All in due time," Biden said. "There will be plenty of time. We'll let [Romney's] statements speak for themselves for now."
