Steve Scalise on climate change: Earth's temperature "goes up and down"
Two years ago House Minority Whip Steve Scalise suffered a life-threatening wound when a gunman opened fire during a practice for the congressional baseball game. His new book “Back in the Game: One Gunman, Countless Heroes, and the Fight for My Life” tells the story of the shooting. Rep. Scalise joins "CBS This Morning" to discuss whether climate change plays a role in Louisiana's ongoing land loss, President Trump's controversial comments about using foreign dirt and the escalating tensions in Iran.
