On Thursday, Hillary Clinton packaged a major new school policy proposal as an attack on her rival, Donald Trump.
"Donald Trump has made no apologies to the growing list of people that he has attempted to bully since the launch of his hate-filled campaign," read the press release from the Clinton campaign about a new $500 million initiative called "Better than Bullying."
In order to get the money, states would have to pass comprehensive anti-bullying laws and form plans to use school-based interventions like social and emotional learning curricula, or hiring more school counselors.
Under the proposal, the federal government would help pay for those programs by contributing $4 for every $1 put up by states.
The emotional resonance is clear. But how good is the evidence for calling bullying an "urgent crisis," as the Democratic nominee's campaign did? Never mind blaming a presidential candidate for a day-to-day increase in bullying?
Here's some fact-checking:
Bullying is not especially prevalent.
In 2013, according to the latest, nationally representative federal statistics, 1 in 5 teenagers reported being bullied at school. That's actually down from 27 percent in 2011. Physical bullying, like being pushed, shoved, tripped or spit on, happened to just 6 percent of teens in the most recent survey, and only a tiny fraction of those said that they were seriously injured.
The most common experiences reported were students being "made fun of, called names, or insulted" (13 percent), and being the "subject of rumors" (also 13 percent).
The survey did not ask how many times these things happened, so it's hard to say how much they define the school experience of the students in question.
And there's little proof it's growing because of Trump.
On the trail, in a debate and in campaign literature, including the announcement this week, Clinton cited an April 2016 publication by the Southern Poverty Law Center. In the survey, titled "The Trump Effect," teachers reported incidents of ethnically and racially motivated bullying by students connected with Donald Trump's campaign rhetoric.
NPR Ed was among those covering the report. But, as we noted at the time, it is basically anecdotal and not nationally representative; the teachers who answered had previously been in contact with the law center, and thus were more likely to be concerned about racial issues in the first place.
Bullies aren't solely to blame for what we call bullying.
"I'm not pleased with the word bullying," says Jonathan Cohen, who works on ways of improving how students and educators treat each other. He is the co-founder and president of the National School Climate Center.
"More often than not," he says, a student who comes to school and picks fights is struggling with severe adversity at home and may be in need of intervention and support as much as his or her victims. Cohen says this could be an issue with how some anti-bullying laws are written, if the in-school behavior of struggling students becomes criminalized.
His research also focuses on the responsibility of bystanders, including educators who may look the other way when a student is repeatedly victimized.
Bullying doesn't just happen at school.
Cyberbullying is an extremely hot topic, but still a fairly rare experience. In that same 2013 report, 7 percent of students said they had been targeted online with unwanted messages or invasions of privacy.
Clinton's proposed initiative includes funding to make the Internet "a safer space," but in practice, schools have limited resources to intervene when students are targeting each other on their own time, and educators may be hamstrung by concerns about privacy or surveillance.
