That whole bit with the photo was unnecessary, really - the whole thing could've been explained away by the simple fact that SUPERMAN HAS SUPER-SPEED. He could've easily swooped up Clark, conducted the interview with him, dropped him back off in Metropolis, and gotten to the White House with plenty of time to spare. I mean, he zips around the world every day as part of his daily routine - a quick back-and-forth from Metropolis to a Pacific island is nothing to him.
