From CBS News' Maria Gavrilovic:
(MONROE, MICH.) - When asked to respond to Sarah Palin's announcement today that her 17-year-old daughter is pregnant, Barack Obama sternly said the story is irrelevant to the presidential campaign.
"I think peoples families are off limits and people's children are especially off limits."
Obama addressed the press after he attended a Labor Day picnic here. Although he intended to give a statement on Hurricane Gustav, Obama was quickly asked about Bristol Palin's pregnancy.
"My mother had me when she was 18 years old," Obama said, adding that families should deal with these issues privately. "That shouldn't be the topic of our politics, and I hope that anybody who is supporting me understands that's off limits."
Obama said he was offended by comments from a McCain advisor suggesting that his campaign may have been spreading rumors about Palin on the internet.
"Our people were not involved in any way in this and the will not be. And if I ever thought that it was somebody in my campaign that was involved in something like that, they'd be fired."
