Federal prosecutors name former Rep. John Doolittle as an unindicted co-conspirator in a corruption case against one of Doolittle's former aides.

In documents filed in U.S. District Court in Washington, D.C., last week, the government also alleged Doolittle's wife, Julia, and nine other people were co-conspirators of Kevin A. Ring.

Neither Doolittle, who last year did not seek a 10th term representing the sprawling 4th Congressional District, nor his wife has been charged with a crime.
