A day after 17 people were killed and many more were injured in the mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida, on Wednesday, former President Barack Obama has responded to the attack on Twitter. In Thursday's post, he expressed his sympathy for the victims, survivors, and their families, before calling for gun control reform.

"We are grieving with Parkland. But we are not powerless. Caring for our kids is our first job. And until we can honestly say that we're doing enough to keep them safe from harm, including long overdue, common-sense gun safety laws that most Americans want, then we have to change," he wrote.

Obama's response to the shooting took a markedly different tone than that of his successor. Immediately after news broke of the shooting on Wednesday, President Donald Trump tweeted, "My prayers and condolences to the families of the victims of the terrible Florida shooting. No child, teacher or anyone else should ever feel unsafe in an American school." On Thursday morning, Trump took to Twitter once again, this time to comment on the shooter's mental health and history of behavioral issues. Later that day, he made a public address about the tragedy in which, yet again, he failed to mention firearms or gun control.

"Our administration is working closely with local authorities to investigate the shooting and learn everything we can. We are committed to working with state and local leaders to help secure our schools, and tackle the difficult issue of mental health," he said, according to CNN. "Later this month, I will be meeting with the nation's governors and attorney generals, where making our schools and our children safer will be our top priority. It is not enough to simply take actions that make us feel like we are making a difference. We must actually make that difference."

Following Wednesday's tragedy, many celebrities made the choice, like Barack Obama, to call for common-sense gun control laws rather than simply offering "thoughts and prayers," including Yara Shahidi, Jimmy Kimmel, and Kim Kardashian West. "We owe it to our children and our teachers to keep them safe while at school. Prayers won't do this: action will. Congress, please do your job and protect Americans from senseless gun violence," Kim tweeted that afternoon.
