No surprise here. From the Washington Times, :
Congressional leaders have been told that federal lawmakers and the U.S. Capitol, in addition to five financial centers identified last week, are targets for attack by al Qaeda terrorists.
Frances Townsend, homeland security adviser at the White House, and Sen. Joseph R. Biden Jr., Delaware Democrat, both appearing on CBS’ “Face the Nation,” confirmed the threats and their extent as officials remain concerned about pre-election terrorist attacks, including abductions and assassinations.
The disclosures helped explain traffic checkpoints and other tighter security imposed last week around Capitol Hill.
When asked directly by interviewer Bob Schieffer whether “there have been some threats against the Capitol and members of Congress,” Mrs. Townsend replied “yes.”
Mrs. Townsend confirmed that the previously undisclosed threats to Capitol Hill are part of a “continuing threat stream” of intelligence.
“We knew that al Qaeda was practiced in the training camps for assassinations and kidnappings, and there are a number of others like that that are continuing threat streams,” she said.
