Senator Barack Obama is reportedly the subject of a $100 million FBI security operation after the Democratic presidential nominee was named as a target in a series of death threats from at least three White supremacists organizations; the National Socialist Vanguard, the American Nazi Party, and the Ku Klux Klan. The move, ordered by Homeland Security director Michael Chertoff, is the biggest ever security operation surrounding a candidate for president. Obama, his wife Michelle, and the couple’s two daughters are under round-the-clock protection from the Secret Service.

“All three groups are seen as posing a threat. But the Klan, in particular, has a nucleus of supporters who are prepared to pursue violence to get their message across,” says an operation insider. “Certain characters would be making a very big mistake if they tried to follow through any of these nasty threats.”
