Bush's approval ratings drop to their lowest point ever.

So...

Yup.

Federal officials have information suggesting that al Qaeda has people in the United States preparing to mount a large-scale terrorist attack this summer, sources familiar with the information said yesterday.

Attorney General John D. Ashcroft and FBI Director Robert S. Mueller III intend to hold a joint news conference this afternoon to discuss the threat and to ask Americans to watch for several suspected al Qaeda operatives who may be in the country, officials said.

The concerns are driven by intelligence deemed credible that was obtained about a month ago indicating an attack may be planned between now and Labor Day.
