But the predictable reaction quickly got personal.
The first lady sat in the audience to listen to their conversation.
"She has asked him to tone down his tweeting", the CNN contributor explained. "Only plausible explanation here is, Melania suffered oxygen deprivation to the brain". After clips of her speech (as seen below) made their way around the internet, angry Twitter users took to the thought-sharing platform to slam Melania as a "hypocrite".
She told the summit at the Health Resources and Services Administration building in Rockville how impressed she was by their "deep understanding of how important it is to be safe" and said she was "inspired by their honest commitment to reducing peer-to-peer bullying through kindness and open communication".
She said that everyone attending shared one goal: "to pave a smooth way forward for our children, our next generation".
Grisham noted to the DailyMail.com that her job as communications director it to make sure reporting on the first lady is accurate. He has called people "stupid", "dummy" and "loser" hundreds of times on his Twitter account over the years.
President Donald Trump may be notorious for using his Twitter handle to bully and insult, but that's not deterring first lady Melania Trump from speaking out against cyberbullying. He called former CIA Director John Brennan a "political hack".
"I am going to do whatever I can to try and prevent these abuses occurring in the future and if that means going to court I will do that", added Brennan, who served under Presidents Obama and George W. Bush.
He had spent part of his morning launching a fresh round of insults on Twitter, calling special counsel Robert Mueller "disgraced and discredited" and labelling former Central Intelligence Agency director John Brennan a "hack" and the "worst Central Intelligence Agency director in our country's history".
Without a hint of irony, she told the crowd: "Let's face it, most children are more aware of the benefits and pitfalls of social media than some adults, but we still need to do all we can to provide them with information and tools for successful and safe online habits". Many people pointed out that her speech came conveniently just days after President Donald Trump, 72, dragged his former White House aide, Omarosa Manigault, 44, on Twitter, calling her "a dog" in one of his many lewd tweets.
"In today's global society, social media is an inevitable part of our children's daily lives", the first lady said.
'It can be used in many positive ways, but can also be destructive and harmful when used incorrectly. She unveiled her Be Best campaign, focused on the needs of children, in May.
"I encourage technology and social media companies, schools and community groups, to establish more opportunities for children", she said. Her Be Best campaign has emphasized the responsibility of adults in ensuring children's well-being.
