Forever First Lady Michelle Obama says she is “in awe” of the student activists who are advocating for gun reform in the wake of the tragic school shooting in Florida that left 17 people dead.

“I’m in total awe of the extraordinary students in Florida. Like every movement for progress in our history, gun reform will take unyielding courage and endurance. But @barackobama and I believe in you, we’re proud of you, and we’re behind you every step of the way,” she tweeted on Wednesday.

Obama’s words are in response to the actions and heartfelt messages of young people all over the country who are speaking out about gun violence in schools. Some of the teens currently leading the charge for this effort are survivors of the high school shooting that left 17 people dead earlier this month in Parkland, FL.

The suspect in that rampage, Nikolas Cruz, used an assault weapon to injure and kill staff and students at his former high school. The tragedy has revived conversations about gun reform.

Former President Barack Obama issued a short statement on Twitter in the wake of the incident, calling for “common sense gun safety laws.”

This is in stark contrast to comments from current President Donald Trump who wants to arm teachers with concealed weapons.
