'It was depleted. Everything was old and exhausted and I came in and I had to fix it and I'm in the process of spending tremendous amounts of money.
In her new memoir, titled Becoming, Obama dismissed the so-called "birther" conspiracy, describing it as concealed racism, Fox News reports.
"It was an expression of hatred that had generally been kept out of polite company, but still lived in the marrow of our supposedly enlightened society - alive and accepted enough that someone like Donald Trump could afford to be cavalier about it", she writes, according to the Post.
Becoming is out November 13.
Ahead of the former first lady's much-anticipated memoir release, some juicy highlights surfaced in the media. Obama (54) will head out on a multi-city arena tour to promote the memoir, with celebrity friends like Oprah Winfrey and Reese Witherspoon tapped to moderate the events.
The comments were some of Michelle Obama's most direct aimed at the current President, whom she has mostly avoided criticising since leaving the White House past year.
Some accused Michelle Obama of hypocrisy. She writes lovingly of her family and gives a detailed account of her courtship with her future husband, whom she met when both were at the Chicago law firm Sidley Austin LLP; she was initially his adviser.
Trump, from his White House office on Thursday, October 1, said that his government was preparing to reform the nation's asylum practices and took on the thousands of migrants fleeing the dangers in central America, heading toward the US.
Considering her quote, "When they go low, we go high", it's unlikely Michelle Obama will respond to Trump again. She also thought his picture had a "whiff of geekiness".
"I can't blame her".
Their first kiss set off a "toppling blast of lust, gratitude, fulfilment, wonder", she wrote.

The remarks faded from the news, but Mrs Obama sensed lasting damage, a perception that she was "disgruntled and vaguely hostile".
The Obamas have said they will donate a "significant portion" of their author proceeds to charity, including the Obama Foundation.
"It turns out that even two committed go-getters with a deep love and robust work ethic can't will themselves into being pregnant", she writes.
Last year, she launched a program to help empower girls worldwide through education.
