Melania Trump Will Attend Bullying Prevention Summit Days After President Tweeted Omarosa Is a 'Dog'

First lady Melania Trump will attend a cyberbullying summit next week, just days after President Donald Trump tweeted that his former White House aide Omarosa Manigault Newman is a "dog."

Melania Trump will address "the positive and negative effects of social media on youth" in Maryland, the White House said Thursday, according to the Associated Press.

The first lady will also participate in a panel with representatives from several unnamed social media platforms in the Federal Partners in Bullying Prevention Cyberbullying Prevention Summit, to take place in Rockville on Monday.

Two days prior to Melania Trump's plans being unveiled, the president used Twitter to bash Manigault Newman, whose book Unhinged: An Insider's Account of the Trump White House released Tuesday details her firing and claims he used the n-word on The Apprentice show, among other scathing allegations.

"When you give a crazed, crying lowlife a break, and give her a job at the White House, I guess it just didn't work out. Good work by General Kelly for quickly firing that dog!" the president tweeted.

Melania Trump has been criticized for choosing to focus her efforts on tackling cyberbullying, while her husband avidly uses Twitter to bully his opponents. The president has called not only Manigault Newman a "dog," but likened more than a half-dozen others to canines including former FBI Director James Comey, former Acting Attorney General Sally Yates, former Director of National Intelligence James Clapper and former Republican nominee Mitt Romney.

The first lady launched her "Be Best" initiative focusing on children's well-being, social media use and fighting opioid abuse, in May.

"Today we pledge to be best—for our families, our communities and our nation," the president said after her speech, and signed a proclamation declaring it "Be Best" day.

Melania Trump's spokeswoman Stephanie Grisham did not immediately respond to a request for comment from Newsweek on Thursday regarding the timing of her summit plans.

Grisham earlier this month tweeted, "#BeBest is a sincere campaign meant to help children. Not something for @CNN to use to mock @POTUS."

Manigault Newman said in her book that Melania Trump "is counting every minute" until her husband is "out of office and she can divorce him."

"Taken as a whole, all of her style rebellions have served the same purpose, and not only misdirection and distraction—strategies her husband knows all too well," Manigault Newman wrote of the first lady's fashion choices. "I believe Melania uses style to punish her husband."
