Living in one's imagination

The Politico reports:

[V.P. Biden said] earlier this week on CNN that he and President George W. Bush once had an exchange in the Oval Office, where Bush said, "Well, Joe ... I'm a leader,” and Biden responded: “Mr. President, turn around and look behind you. No one is following.”

No one confirms Biden's claim and Karl Rove disputes it strongly:

"It didn't happen," Rove said. "It's his imagination. It's a made-up, fictional world. He ought to get out of it and get back to reality.”

PREVIOUSLY, U.S. Rep. Steve Kagen (D-Wis) took pleasure in his similar claims to have had confrontational in a meeting with, coincidentally, Karl Rove, as discussed in "Adolescents in the (US) House."
