Anderson Cooper began Monday's two-hour broadcast of Anderson Cooper 360 with a tribute to the 50 victims of the tragic mass shooting last weekend at Orlando's Pulse nightclub by reading their names one by one, and conspicuously leaving out the name of the attacker. Cooper's emotions got the better of him during the reading as he choked back tears several times. We barely made it through this video ourselves, and we're sure you'll feel the same way.
