Michelle Obama's mom, Marian Robinson: WH "Live-in Grandma"

First Lady Michelle Obama took her mom, Marian Robinson and daughters Malia and Sasha on her recent trip to China, a peg for a Washington Post story on Mrs. Robinson, who moved from her South Side Chicago home to the White House after son-in-law Barack Obama was elected president.

Excerpt, from story by Krissah Thompson and Juliet Eilperin: “For six days in China, the least-public resident of the White House was a central figure on the public stage. Overseas trips like the one Robinson took with her daughter and granddaughters last week provide an uncommon glimpse into their family dynamic and the critical role she has continued to play in the first family.”
