AMY GOODMAN: Seymour Hersh, I want to thank you for being with us, Pulitzer Prize-winning investigative journalist, speaking to us from Washington, D.C. We will link to your latest piece in the London Review of Books, headlined "Whose Sarin?" at democracynow.org. When we come back, Reverend Jesse Jackson joins us before he heads to South Africa. Nelson Mandela will be laid to rest this week. He died last week at the age of 95. Stay with us.
