Federal agents searched the home of U.S. Sen. Ted Stevens on Monday, focusing on records related to his relationship with an oil field services contractor jailed in a public corruption investigation, a law enforcement official said.

Stevens, 83, has been under a federal investigation for a 2000 renovation project more than doubling the size of his home in Girdwood that was overseen by Bill Allen, a contractor who has pleaded guilty to bribing Alaska state legislators.

An e-mail statement issued by Stevens through his Washington, D.C., spokesman said federal agents had alerted his attorneys that they wanted to search his home.

Stevens, who is the longest-serving Republican in Senate history, said the interests of justice would be best served if he commented after the investigation. "I continue to believe this investigation should proceed to its conclusion without any appearance that I have attempted to influence its outcome," Stevens said. "The legal process should be allowed to proceed so that all the facts can be established and the truth determined."
