A federal grand jury reportedly has issued subpoenas in a probe involving Sen. John Ensign of Nevada.
According to one subpoena obtained by a Las Vegas television station, recipients were ordered to testify March 31 in Washington, D.C., and to turn over documents relating to the Republican senator.
TV station KLAS reported Thursday that the subpoenas went to six unnamed Las Vegas businesses. The subpoena posted on the station's Web site blacks out the recipient's identity.
The FBI and Senate Ethics Committee are investigating whether Ensign tried to limit political damage from an affair he had with the wife of one of his Senate aides by conspiring to find lobbying work for the aide after he left Ensign's staff. The affair ended in 2008; Ensign is married.
