From today's WaPo,
In April, Homeland Security Secretary Tom Ridge announced that al Qaeda terrorists might strike during this week's presidential inauguration festivities in Washington. The warning was part of a drumbeat sounded by U.S. officials throughout 2004 that terrorists were seeking to launch attacks both during and after the election season.
Nine months later, the threat level has been lowered, and Ridge, speaking at a news conference last week, said there is no evidence of a plot to disrupt President Bush's inauguration. Previous warnings, Ridge explained, stemmed from threat reports tied to the elections -- not to the inauguration more than two months later.
