Melania Trump's Anti-Bullying Slogan #BeBest Trends After Donald Trump Mocks 16-Year-Old Climate Activist Greta Thunberg

After President Donald Trump mocked 16-year-old climate activist Greta Thunberg on Twitter, users of the social media platform hit back at him with a lesson from his wife, Melania Trump: #BeBest.

The anti-bullying hashtag created by the first lady was trending on Twitter after the president shared a video on Monday night of Thunberg urging global leaders at the United General Assembly Climate Action Summit to step up the fight against climate change—and made a seemingly sarcastic comment.

"She seems like a very happy young girl looking forward to a bright and wonderful future," the president tweeted. "So nice to see!"

Songwriter Holly Figueroa O'Reilly, who founded the Blue Wave Crowdsource supporting Democratic candidates, tweeted at the president, "Be best, a**hole," along with the hashtag #GretaThunbergOutdidTrump.

O'Reilly, who sued the president for blocking her on Twitter, then addressed the first lady, whose "Be Best" initiative aims to help children by boosting their well-being and fighting opioid use and cyberbullying.

"Hey, @FLOTUS, is this what you meant when you said #BeBest?" O'Reilly tweeted. "Your husband is mocking a 16-year-old girl w/autism. If people mock [Melania and Donald's son] Barron, we on the left are the first to condemn them. Why are you silent in this?"

Writer and blogger Andy Ostroy replied to the president by mentioning Melania Trump and using her hashtag as well.

"Hey @FLOTUS...your sociopath husband is mocking/bullying a little girl," Ostroy tweeted. "Ya probs need to go all #BeBest 'n 'shit on his cowardly a**."

Nebraska state Senator Megan Hunt replied to the president by referring to accusations that he has acted inappropriately toward girls.

"Way to #bebest," Hunt tweeted. "I guess you don't like children unless they're in a dressing room at a pageant."

The president mocked Thunberg, who is on the autism spectrum, after a GIF went viral of the young Swedish activist staring him down as he walked by her in the United Nations lobby.

In a speech before the United Nations earlier on Monday, Thunberg criticized its proposal to cut emissions in half over the next 10 years as not aggressive enough.

"This is all wrong," Thunberg said. "I shouldn't be up here. I should be back in school on the other side of the ocean. Yet you all come to us young people for hope? How dare you!"

Thunberg continued, "You are failing us. But the young people are starting to understand your betrayal. The eyes of all future generations are upon you. And if you choose to fail us, I say we will never forgive you. We will not let you get away with this."

The United States was not invited to the climate summit due to its level of greenhouse gas emissions, but Trump crashed the meeting for 10 to 15 minutes.
