The King's English

In the December 4, 2008, New York Times, there is an interview with First Lady Laura Bush. She is quoted thusly:

"I just like to think about the people who lived here [in the White House] before me," she said. "When both George and me walked through all of these rooms, these rooms downstairs as well as our residence, we're very aware of all the presidents before us."

When both George and me walked through all of these rooms? When both George and me walked through all of these rooms? When both George and me walked through all of these rooms?

Help!
