On Tuesday, the Democratic presidential debates were held in Ohio.
Sparks flew between Beto O'Rourke and Mayor Pete Buttigieg.
O'Rourke is pushing for a mandatory gun buy-back program.
Buttigieg said that O’Rourke’s gun buyback proposal could hurt Democrats appeal with moderate voters.
Buttigieg has called the plan a "shiny object" that distracts from implementation of existing gun laws.
The Mayor also slammed O'Rourke for a lack of detail and clarity in his gun buy-back plan.
He closed by telling O'Rourke “I don’t need lessons from you on courage.”
