Former first lady Michelle Obama Michelle LeVaughn Robinson ObamaBlack stars reimagine 'Friends' to get out the vote Obama shares phone number to find out how Americans are planning to vote Michelle Obama: 'Don't listen to people who will say that somehow voting is rigged' MORE kicked off her book tour on Tuesday, where she was joined by Oprah Winfrey in Chicago to discuss her memoir, "Becoming."

The Associated Press reported that a sold-out crowd of 14,000 people cheered the two women as they took the stage at the United Center. Obama discussed her time in the White House, her childhood in Chicago and some details left out of her newly released book.

Obama recounted that she cried on the plane leaving Washington, D.C., on Inauguration Day in 2017, according to the AP, but said it was not because of President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'

"I think it was just the release of eight years trying to do everything perfectly," she said, describing an episode not in the book.

The AP reported that neither Obama nor Winfrey explicitly spoke about Trump during the 90-minute talk, though the first lady's book hits the president in her book for spreading birther conspiracies about her husband.

Winfrey, who has campaigned for Democrats and spoken critically of the president in recent months, suggested Obama's book tour was a sign of positivity amid divided times.

“So many people are feeling uneasy... afraid of the impending darkness,” Winfrey said, according to the AP. “But you all being here tonight is a testament to the light.”

Winfrey this week announced that "Becoming" was the latest pick for her influential book club.

Obama will promote her book in nearly a dozen other cities over the next several weeks. She will be joined by other prominent guests at each stop, including actresses Reese Witherspoon and Sarah Jessica Parker, and former White House adviser Valerie Jarrett.
