President Donald Trump hit back at former first lady Michelle Obama’s criticism of him by taking a shot at his predecessor, before departing Friday morning for Paris.

Obama is out with a new book in which she is highly critical of Trump, writing, “the whole [birther] thing was crazy and mean-spirited, of course, its underlying bigotry and xenophobia hardly concealed. But it was also dangerous, deliberately meant to stir up the wingnuts and kooks.”

She added, “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.'”

“Michelle Obama got paid a lot of money to write a book and they always insist you come up with controversy,” Trump said when confronted with the comments, adding that he would give a controversy right back.

Trump declared, “I’ll never forgive [Barack Obama] for what he did to our United States military by not funding it properly. It was depleted. Everything was old and tired and I came in and I had to fix it.”

He continued, “what he did to our military made this country unsafe.”
