Former first lady Michelle Obama called President Donald Trump "misogynist" and accused him of endangering her family's safety with the "birther" controversy against Barack Obama. In her new book, "Becoming," she said she stopped “even trying to smile” during Trump’s 2017 inauguration.

Michelle, in her new book, also added she had wondered why so many women rejected "an exceptionally qualified female candidate and instead choose a misogynist as their president." The 54-year-old sat down with “Good Morning America’s” Robin Roberts in an interview released Sunday to discuss the change after leaving the White House.

“Someone from Barack’s administration might have said that the optics there were bad, that what the public saw didn’t reflect the president’s reality or ideals,” she wrote, according to ABC. “But in this case, maybe it did.”

“Realizing it, I made my own optic adjustment,” she continued while talking about Trump’s 2017 inauguration. “I stopped even trying to smile.”

When mentioned by Roberts the Obamas have mostly avoided criticizing Trump since leaving the White House last year, Michelle said: “I said what I continue to say — being the commander in chief is a hard job... You need to have discipline. You need to read and you need to be knowledgeable. You need to know history. You need to be careful with your words.”

“But voters make those decisions and once the voters have spoken, we live with what we live with,” she added.

In her book, Michelle criticized Trump, saying she would “never forgive” him for spreading the “birther” conspiracy theory against her husband.

"The whole thing was crazy and mean-spirited, of course, its underlying bigotry and xenophobia hardly concealed," Obama wrote. "But it was also dangerous, deliberately meant to stir up the wingnuts and kooks."

“What if someone with an unstable mind loaded a gun and drove to Washington? What if that person went looking for our girls? Donald Trump, with his loud and reckless innuendos, was putting my family’s safety at risk. And for this I’d never forgive him," she continued.

The "birther" conspiracy first surfaced in 2008 but Trump began stirring it up again in 2011 when Obama began running for re-election.

“I would like to have him show his birth certificate, and can I be honest with you, I hope he can. Because if he can’t, if he can’t, if he wasn’t born in this country, which is a real possibility ... then he has pulled one of the great cons in the history of politics,” Trump had said that year on the Today programme.

Toward the end of his run for president in 2016, Trump admitted he thought Obama was born in the U.S.; however, he never accepted responsibility for his previous actions.

In the book "Becoming," Michelle not only talked about Trump and her life in the White House, but she also opened up about her marriages and revealed she suffered a miscarriage 20 years ago. Addressing the miscarriage during the interview with Roberts, Michelle said she and the former president have gotten marriage counseling in the past to help “talk out our differences.”

“I know too many young couples who struggle and think somehow, there’s something wrong with them,” Michelle said. “I want them to know that Michelle and Barack Obama — who have a phenomenal marriage and who love each other — we work on our marriage and we get help with our marriage when we need it.”

The Obamas used in vitro fertilization to conceive their two daughters, Malia and Sasha.
