Michelle Obama’s eloquence cannot be overstated; in fact, it’s part of the reason why the First Lady has quickly become one of the most influential surrogates for Hillary Clinton’s presidential campaign.

At a campaign event Thursday at Southern New Hampshire University, Obama gave an impassioned speech about Republican nominee Donald Trump’s treatment of women, telling the audience the events of the past week have “shaken me to my core.”

“Last week we saw this candidate actually bragging about sexually assaulting women,” Obama said. “I can't believe I'm saying that a candidate for president of the United States has bragged about sexually assaulting women. I have to tell you that I—I can't stop thinking about this. It has shaken me to my core in a way that I couldn't have predicted.”

Obama told the crowd while she’d “love nothing more” than to ignore Trump and carry on with her standard campaign speech, “it would be dishonest and disingenuous for me to just move on to the next thing like this was all just a bad dream.”

A visibly upset Obama dismissed the Trump campaign defense that his comments are “locker room banter,” delivering a knock-out blow to the Republican candidate:

“This was a powerful individual speaking freely and openly about sexually predatory behavior, and actually bragging about kissing and groping, using language so obscene that many of were worried about our children hearing it when we turn on the TV.”

In a nod to recent allegations that Trump has made unwanted sexual advances on at least 12 women, Obama said she takes Trump’s behavior personally. “I’m sure that many of you do too, particularly the women. The shameful comments about our bodies, the disrespect of our ambitions and intellect, the belief that you can do anything you want to a woman. It is cruel. It is frightening. And the truth is: it hurts.”
