Mrs. Robinson is coming to Washington! Michelle Obama's mother, Marian, who played a crucial role in looking after the Obamas' daughters during the campaign, will move into the White House [1] with the rest of the family.
The first granny hasn't decided whether she will stay permanently. It will probably be a tough decision considering she still lives in the Chicago home where she raised Michelle.
If you're wondering whether Obama will be taking orders from his mother-in-law, you can at least know it won't be the other way around. During his post-election interview [2] with 60 Minutes, Obama was asked whether Marian would be moving in. He said: "Well, I don't tell my mother-in-law what to do. But I'm not stupid. That's why I got elected president, man."
