FBI agents have searched the Oakton, Va., home of Rep. John Doolittle, who is under investigation in the congressional corruption investigation surrounding convicted GOP lobbyist Jack Abramoff, Doolittle's attorney said Wednesday.

The search last Friday focused on records of Doolittle's wife's company, Sierra Dominion Financial Solutions Inc., said attorney David Barger.

Doolittle's wife, Julie Doolittle, was on retainer for Abramoff from 2002-2004 for event-planning work.

"The congressman fully supports his wife in this matter and we're optimistic that truth will win out in the end," Barger said. He refused further comment.

Doolittle, a Placer County conservative, has numerous ties to Abramoff beyond his wife's work for the lobbyist.

They include accepting campaign cash from him and interceding on behalf of his Indian tribe clients.
