As women around the world celebrated International Women’s Day on Wednesday, Hillary Clinton added her own sweet tweet to the mix.

The former secretary of state and presidential candidate quote-tweeted an image that appears to feature a note from a student found on a classroom floor by a fourth-grade teacher. The note reads: “Do you want to join a club for female empowerment. We are the leaders.”

Twitter user Elly originally shared the image on Monday. By Wednesday afternoon, it had 40,000 retweets and 140,000 favorites on Twitter.

My fourth grade teacher friend found this under one of her students' desks. <3 <3 <3 pic.twitter.com/7NSxIa6ujn — Elly (@SMLXist) March 6, 2017

Clinton, whose account featured a red avatar appearing to honor “A Day Without A Woman,” linked to the tweet and wrote that young girls, like the one who wrote that note, are who she’s thinking about on this International Women’s Day.

On #InternationalWomensDay I'm thinking about this young girl, & all the others like her out there. 💪✨ https://t.co/u1fvzAt1BI — Hillary Clinton (@HillaryClinton) March 8, 2017

Twitter user Elly noted that the letter was discovered by a friend, a teacher. The Huffington Post was directed to contact the school’s communication office for comment, but did not receive a response at the time this article was published.

Elly tweeted the following in response to those questioning the veracity of the tweet.

The fact that so many people refuse to believe that a little girl wants to start a club for female empowerment means we NEED those clubs. — Elly (@SMLXist) March 7, 2017

She went on to include a more thorough tweet thread about what’s happened since the note was found.

Update: My friend has asked me to help form and co-sponsor the club, which has the full backing of the school. — Elly (@SMLXist) March 7, 2017

She talked to the note's author and found that she wants to start the club because boys had been telling her girls can't do what boys can. — Elly (@SMLXist) March 7, 2017

As I've said before, scientific studies show that girls start to feel the effects of gender inequality at ages as young as six. — Elly (@SMLXist) March 7, 2017

Something happened to one girl, and it made her feel bad. Her reaction was to want to stop it from happening to other girls. THAT'S AWESOME. — Elly (@SMLXist) March 7, 2017

“My friend has asked me to help form and co-sponsor the club, which has the full backing of the school. She talked to the note’s author and found that she wants to start the club because boys had been telling her girls can’t do what boys can... Something happened to one girl, and it made her feel bad.
