Florida Georgia Line's Tyler Hubbard has thrown his support behind the End Gun Violence Together campaign launched by Blake Mycoskie of TOMS Shoes -- and he wants his colleagues across country music to join him.

On Nov. 29, Hubbard delivered an impassioned endorsement of the TOMS CEO's new initiative. In a solemn video, he referred to the staggering statistics regarding the 307 mass shootings that took place over the last 311 days in the United States and said that he believes that "we can all come together and all agree that something has to change" by contacting congress and demanding stricter gun laws.

Now, Hubbard is doubling down on that message and asking his peers across country -- including Jason Aldean, Miranda Lambert, Maren Morris, Luke Bryan, Taylor Swift and many more -- to get involved, even if it means stepping outside their comfort zones to lend their social media platforms to the cause.

"To my friends, to my peers, to other artists: I know we've all been affected by gun violence directly or indirectly," he says in a follow-up to his initial video.

"I just want to say it's our time to take a stand, to join together. I know a lot of you guys are on the fence about posting a video, but I just want to challenge you -- either repost my video or shoot your own video and just continue to spread the word."
