Ross reports on ABC NEWS' THE BLOTTER

Senior law enforcement officials said today that the growing signs of a "Summer of '07" terror attack on the U.S. have led the FBI to dispatch dozens of agents to track down new leads across the country.

The report goes on to say: "Although the White House says there is no credible, imminent threat to the United States, the origin of the intelligence that a small group of al Qaeda terrorists was headed to the United States came from a credible intelligence source, who in the past has been reliable, officials said."
