Marian Robinson, Michelle Obama's mother, dies at 86

WASHINGTON — Former First Lady Michelle Obama’s mother, Marian Robinson, has died, according to a family statement shared with NBC News. Robinson was 86 years old.

“She passed peacefully this morning, and right now, none of us are quite sure how exactly we’ll move on without her,” the family statement said.

The family statement is from Michelle and Barack Obama; Craig Robinson and his wife, Kelly; and Marian Robinson’s grandchildren, Avery, Leslie, Malia, Sasha, Austin and Aaron.

“I felt like this was going to be a very hard life for both of them,” she later said in a CBS interview, referring to her daughter and son-in-law. “And I was worried about their safety, and I was worried about my grandkids. That’s what got me to move to D.C.”

In their statement Friday, Robinson's family members said she agreed to leave Chicago with "a healthy nudge."

"We needed her. The girls needed her. And she ended up being our rock through it all," they said.

"She relished her role as a grandmother. ... And although she enforced whatever household rules we’d set for bedtime, watching TV, or eating candy, she made clear that she sided
