Warren later asked the same question to McCain: "What point is a baby entitled to human rights?"
McCain: "At the moment of conception. I have a 25-year pro-life record in the Congress, in the Senate. And as president of the United States, I will be a pro-life president. And this presidency will have pro-life policies. That’s my commitment. That’s my commitment to you."
Warren: "OK, we don’t have to beleaguer on that one. Define marriage."
McCain: "A union — a union between man and woman, between one man and one woman. That’s my definition of marriage."
Obama actually does know that life begins at conception as he let slip last Father's Day. Family Research Council Action President, Tony Perkins takes a closer look at Obama's Father's Day remark and asks Barack Obama: When Does Life Begin?:
Tony Perkins in a June 27, 2008 Reuters Interview:
"While Senator Barack Obama's comments on Father's Day imploring men to take responsibility for their children are commendable, he appears to be unaware of the irony in his statement that 'we need fathers to recognize that responsibility doesn't just end at conception'.
"I would like to ask Senator Obama: if my responsibility as a father began at conception, isn't that when the lives of my children began?
"Senator Obama has voted for numerous laws supporting abortion in his time in the U.S. Senate and the Illinois legislature. He is the co-sponsor of the Federal Freedom of Choice Act, a sweeping piece of legislation that will legalize partial-birth abortion and overturn virtually all federal and state limitations on abortion.
"Senator Obama understands that a father's responsibility does not end at conception, but does he understand that it begins there as well?"
