David Hogg is an American Gun Control Activist and is a student survivor of the Parkland, Florida shooting. Fred Guttenberg is also an American Gun Control Activist whose daughter was killed in the Parkland shooting. This week, they sit down with Joe Walsh to search for common ground regarding gun control… and the horror of being in the middle of a mass shooting. (Please note: this discussion was taped before the school shooting in Uvalde, Texas.)
