People familiar with the investigation said federal investigators are interested in questioning Abramoff about his dealings with DeLay and Ney as well as other lawmakers and officials. Those include Rep. John Doolittle, R-Calif., Rudy and Sen. Conrad Burns, R-Mont., as well as former deputy Interior Secretary Stephen Griles and former top Bush administration contract officer David Safavian, according to the sources, who spoke on condition of anonymity because Abramoff's information is likely to be submitted to a federal grand jury.
