Michelle Obama may have only recently jumped on Hillary Clinton’s campaign trail, but she has already mastered the art of insulting The Orange One Who Must Not Be Named.

Obama mostly stayed on-script at the rally, calling for a “steady,” “measured” and “honest” leader while denouncing misogyny and “not paying taxes.”

But she picked up the fire when she went all in on Trump, ragging on his late-night Twitter rant and his disrespect for veterans with post-traumatic stress disorder. Then, with a tap of her microphone, she burned Trump over his uncanny ability to blame others for his missteps.

“When [Clinton] gets knocked down, she doesn’t complain,” Obama said before tapping on her microphone. “She doesn’t cry foul. No, she gets right back up, comes back stronger for the people who needs her most.”

The mic tap was an apparent nod to Trump’s suggestion that he was given a faulty microphone to sabotage his performance during the first presidential debate.

“When making life-or-death, war-or-peace decisions, a president can’t just pop off or lash out irrationally,” Obama said to the crowd of about 1,400 people. “And I think we can all agree that someone who’s roaming around at 3 a.m. tweeting should not have their fingers on the nuclear codes.”

Obama continued her takedown of the GOP nominee by pointing out that Trump is the type of candidate who “implies that veterans who serve our country so bravely are somehow weak because they’re dealing with the wounds of war.”

CORRECTION: This article initially characterized Trump’s assertion that the microphone was faulty as “unfounded,” and it has been updated in light of a statement from the Commission on Presidential Debates that “there were issues regarding Donald Trump’s audio.”

Editor’s note: Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims — 1.6 billion members of an entire religion — from entering the U.S.
