President Trump routinely touts the surging stock market as one of his accomplishments, but on Monday, first lady Melania Trump went to the floor of the New York Stock Exchange to kick-start the trading day herself.

Melania Trump rang the opening bell at 9:30 a.m., joined by students from the United Nations International School and Stacey Cunningham, the first female president of the Stock Exchange.

The first lady was there to push her Be Best campaign that promotes safe social media use and discourages cyberbullying. “Follow your dreams and be best at what you do,” Trump told the children about Be Best.

The students, a mix of third- and fourth-graders selected by lottery to attend, presented her with a plaque that describes the school’s mission to provide “an inclusive and diverse learning environment in which rigorous international programs foster academic excellence, innovation, creativity, and cross-cultural communications to educate and inspire the students to become an active force in shaping a better world: peaceful, compassionate and sustainable.”

Melania met with the students before the opening bell, shaking hands with them and wishing them a “good morning.”

“Thank you very much for being here,” she told them.

Another one of the students read a letter to her.

“UNIS stands for peace in the world and to make the world a better place. We are very open minded and like to listen to new ideas. We like our ideas to be heard, too. We like to tell people to be kind,” the student said. “Please help UNIS spread the love around the world.”

The first lady was in New York as her husband attended the United Nations General Assembly.

She became the third past or present first lady to ring the opening bell, along with Laura Bush in 2012 and Hillary Clinton in 2009.
