Michelle Obama will not run for the US presidency in 2020, the outgoing First Lady says.
In an interview with Oprah Winfrey, Ms Obama said it's not something she would want her family to go through again.
"No - I'm pretty direct. If I were interested in it I'd say it. I don't believe in playing games.
"People don't really understand how hard this is, and it's not something you cavalierly ask a family to do again."
She told Oprah about the pressure it puts on family. "You run - their lives stop," she said.
"The next family that comes in here - every person in that family - every child, every grandchild - their lives will be turned upside down in a way that no American really understands."
She spoke of how painful the 2016 United States presidential election was, and acknowledged she went to sleep on election night without knowing the final outcome.
"I got up and I looked at my iPhone, and I saw it.
"I kind of felt like how things were going by the time I went to bed.
"So mentally, I'd already kind of digested it before I actually read it."
She and her husband - outgoing President Barack Obama - are determined not to speak negatively about the transition to a Trump leadership.
"No matter how we felt going into it, it is important for the health of this nation that we support the Commander in Chief."
When asked about achieving the goal of bringing hope, Ms Obama said her husband was successful because the contrast can be felt now.
"Now we're feeling what not having hope feels like. You know? Hope is necessary. It's a necessary concept."
