What is the impact of ending ban on transgender soldiers?

The Pentagon has lifted its ban on transgender troops. Defense Secretary Ash Carter announced the move Thursday and officials said health services for trans soldiers, including sexual reassignment surgery, will be covered in 90 days. Of the military’s 1.5 million active duty soldiers, an estimated 2,500 to 7,000 are trans. Hari Sreenivasan talks with John Yang about the historic change.
