Obama writes that she assumed Trump was “grandstanding” when he announced his presidential run in 2015, expresses disbelief over how so many women would choose a “misogynist” over Hillary Clinton, “an exceptionally qualified female candidate,” and recalled how her body “buzzed with fury” after seeing the infamous “Access Hollywood” tape, in which Trump brags about sexually assaulting women.

She also slammed Trump’s “birther” campaign questioning her husband’s citizenship, calling it bigoted and dangerous, and saying it put her family at risk of being harmed.

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