Our take: First Lady, Michelle Obama, shares the support that her family gives each other as they make sure that family comes first. Mary Bruce, from ABC News, explains more about the exclusive interview that Cynthia McFadden had with Obama:

"First lady Michelle Obama is campaigner-in-chief when it comes to stumping her husband and a key asset on the trail, yet she rarely talks about the inner workings of her marriage.

'Nightline' was granted wide-ranging access to Mrs. Obama, who opened up about adjusting to life in the White House, but said she no longer has any doubts that they are doing what's best for their family and the country, and is looking forward to another four years."
