Good Morning America's 7 Wonders of America kicked off today, with anchor Robin Roberts at the Washington Mall in Washington, D.C. Joining Roberts were two special guests, President George W. Bush and First Lady Laura Bush. Insiders tell TVNewser this was just the second ever live morning show interview of the President — the first being with GMA's Diane Sawyer after Hurricane Katrina.

The interview focused on the economy and gas prices, 2008 presidential predictions and of course, the wonder of the locale.

"Lincoln is my favorite president, of course, other than my dad," said Bush during the interview.

Notably absent from the ABC show this morning was weather anchor Sam Champion, who was said to be en route to the next Wonder location for tomorrow morning. Any guesses for the long, America-based trek?

> Update: A TVNewser tipster finds at least one more live interview, with NBC's Matt Lauer.
