Barack Obama started his morning off by addressing the tragic shooting that has gripped Broward County, Florida, on Thursday, February 15. For what would amount to only his third time on the platform all year, the former Commander-In-Chief took to Twitter with a message that reminded the nation of its duty to its children - and called upon lawmakers to take action within their legislative chambers.

"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 post followed a series of scattered tweets President Trump has put out to express his condolences to the families of the 17 people who lost their lives, and to preach the importance of paying attention to signs of mental illness.

The former U.S. President has long been known for his emotional responses to school shootings. Back in 2012, he shook up the nation with a series of speeches during which he teared up while expressing his grievance over the elementary school children lost in Sandy Hook, Connecticut. Along the way, he's remained steadfast in his advocacy for sensible gun regulations.
