Joy Reid begins this episode of The ReidOut remembering the victims of the Uvalde, Texas elementary school shooting, and lambasting the Republican politicians who claim that demands to address gun violence and end such violence in schools amount to politicizing this tragedy. "So to hell with anybody who says 'Don't politicize this,' because these deaths--until we change and stop letting this minority of ghouls rule us--this is who we are," Joy says. Anti-gun violence activist Fred Guttenberg, whose 14-year-old daughter Jaime was murdered in the mass shooting at Marjorie Stoneman Douglas High School in Parkland, Florida in 2018, joins The ReidOut. Plus, Sen. Sheldon Whitehouse joins Joy on what seats would need to be flipped in the Senate to pass legislation that the majority of Americans want, such as common sense gun control--and it is only four or five, according to the senator. All this and much more in this edition of The ReidOut on MSNBC.
