The Senate vote on the health care bill is off — for now. We focus on Maine, where Senator Susan Collins has been a vocal opponent of the proposal. And what happens to family members who witness police shootings? Guests: Jennifer Steinhauer, who covers Congress; Lee Umphrey, the chief executive of a health center in Maine; Yamiche Alcindor, who covered the shooting of Philando Castile. Caitlin Dickerson is our host; Michael Barbaro is on vacation. For more information on today’s episode, visit http://nyti.ms/2uo8uVi.
