Sen. John Ensign's former administrative assistant, whose wife had an affair with the senator, was indicted Thursday for allegedly lobbying Ensign and his staff in violation of federal conflict of interest laws.
Douglas Hampton is charged in connection with lobbying he did on behalf of a Las Vegas airline company and an energy company.
Federal law prohibits a senior Senate aide from lobbying the Senate for one year after terminating employment.
The affair with Hampton's wife has sidetracked the Republican senator's political career. Ensign announced this month that he would not seek a third term.
Ensign has said the affair with Cynthia Hampton began during a rocky time in his marriage in December 2007 and continued until August 2008. Cynthia and Doug Hampton left their jobs with Ensign in May 2008.
When Doug Hampton found out about the affair between his wife and the senator, Ensign helped line up jobs for Hampton with campaign donors.
According to the indictment, Hampton lobbied on behalf of Las Vegas-based Allegiant Air and for NV Energy.
Hampton's lawyer, Dan Albregts, declined to comment about the latest development in the long-running probe surrounding Ensign and the Hamptons.
A call to Ensign's office was not immediately returned.
The indictment marks the second reversal of fortune for those involved in the Justice Department inquiry, which followed revelations of Ensign's affair with Hampton's wife.
Ensign himself came under investigation on whether he conspired with Hampton to violate the lobbying restriction.
Last December, the Justice Department disclosed to the senator that it no longer viewed him as a target in the probe.
On behalf of Allegiant Air, the indictment says, Hampton sought the assistance of Ensign and a legislative aide to Ensign to convince the U.S. Transportation Department to reconsider its position on a fuel surcharge pricing issue. Hampton allegedly sought the assistance of Ensign and his staff to help schedule a March 2009 meeting involving the secretary of transportation and executives from the airline company.
On behalf of NV Energy, the indictment stated, Hampton sought the assistance of Ensign and his chief of staff to expedite the release of a U.S. Interior Department environmental impact statement regarding a company coal-fired power plant.
The lobbying effort was designed to allow the energy company to move forward on its delayed proposal to build the plant.
If convicted, Hampton, 48, would face up to five years in prison on each of the seven counts of violating federal conflict of interest laws. Hampton also would face a maximum fine of $250,000 per count. Hampton faces a court appearance in federal court in Washington next Thursday.
The lobbying restrictions are contained in the Honest Leadership and Open Government Act. The law is aimed at slowing the revolving door between congressional employment and lobbying activities following the departure of aides from government.
