On Monday night, Trump dug into Clinton in a rally in Grand Rapids, Mich., saying that her bathroom break during Saturday’s Democratic debate was “too disgusting” to talk about, and that she got “schlonged” by President Obama in the 2008 primaries. Now, the Clinton campaign is turning Trump’s remarks into campaign material, the New York Times reports.

Clinton allies like Emily’s List have taken the opportunity to send out an open letter saying that Trump “went too far.” And the Clinton campaign’s communications director Jennifer Palmieri shot out a tweet that garnered over a thousand likes and retweets:

We are not responding to Trump but everyone who understands the humiliation this degrading language inflicts on all women should. #imwithher

On Tuesday at a rally in Iowa, Clinton responded to a question from a young girl about bullying by talking about Trump: “You are looking at somebody who’s had a lot of terrible things said about me and I am well aware of the fact that it’s really easy to do that,” Clinton said, adding, “We shouldn’t let anybody bully his way into the presidency.”
