Greta Thunberg Expertly Claps Back at Donald Trump's 'Bullying' Tweet

Greta Thunberg expertly clapped back at Donald Trump on Tuesday after the President was called out on social media for "bullying" the autistic 16-year-old.

After the teenager gave a furious and tear-filled speech to the UN, demanding world leaders take action on climate change, Trump tweeted a link with the clearly-mocking caption: "She seems like a very happy young girl looking forward to a bright and wonderful future. So nice to see!"

But the young Swedish activist effortlessly absorbed the 73-year-old's jibe by updating her Twitter bio to: "A very happy young girl looking forward to a bright and wonderful future."

Withing minutes #GretaThunbergOutdidTrump was trending on Twitter — as was #BeBest, as users highlighted Melania Trump's deafening silence on the issue by using her supposed anti-bullying hashtag.

"Hey, @FLOTUS, is this what you meant when you said #BeBest? Your husband is mocking a 16-year-old girl w/autism," wrote Holly Figueroa O'Reilly, who once successfully sued the President for blocking her on Twitter. "If people mock Barron, we on the left are the first to condemn them. Why are you silent in this?"

Many pointed out it wasn't the first time the President was accused of mocking someone with a disability, as gifs of his infamous 2015 "impression" of New York Times reporter Sege Kovaleski — who suffers from arthrogryposis — began to recirculate.

Meanwhile Fox News was forced to apologize and cut ties with one of its contributors, conservative podcast host Michael Knowles, after he described Greta as a "mentally ill Swedish child."

"The comment made by Michael Knowles who was a guest on The Story tonight, was disgraceful — we apologize to Greta Thunberg and to our viewers," the network said in a statement, adding that Knowles will not be booked as a guest in the future.

Fox host Laura Ingraham also came under fire on Twitter for comparing Greta to Stephen King's "Children Of The Corn" — most noticeably from her own brother.

"Clearly my sister's paycheck is more important than the world her three adopted kids will inherit," Curtis Ingraham tweeted. "I can no longer apologize for a sibling who I no longer recognize. I can and will continue to call out the monstrous behavior and the bully commentary born out of anger."

For the most part, the Internet was fully supportive of Greta's efforts and impassioned speech.

"You have stolen my dreams and my childhood with your empty words," she angrily told the UN. "People are suffering, people are dying, entire ecosystems are collapsing. We are in the beginning of a mass extinction and all you can talk about is money and fairytales of eternal economic growth."

Even more popular online was the death stare she was caught giving the President as he arrived at the forum, which was quickly meme-ified ad-infinitum.
