A New York man spent "tens of thousands of dollars" in Chicago newspaper advertising this week to convince people that President-elect Barack Obama is not a natural-born citizen of the United States.
Ads placed by the We The People Foundation repeated allegations heard throughout the campaign challenging Obama's citizenship.
The Chicago Tribune, which ran the ads, reported Wednesday that the Obama campaign provided the paper with a copy of the president-elect's birth certificate, but still, the paper said, "some critics remain dubious."
