As soon as federal regulators slapped Clear Channel Communications with a nearly half-million-dollar fine for indecent broadcasts, the radio station owner announced several changes to make sure that never happens again.

First, of course, Clear Channel dumped shock jock Howard Stern.

But the company also appointed a new head of its lobbying operation.

Jessica Marventano was named head of Clear Channel’s Washington office last week, replacing one of her former colleagues.

The move is part of the company’s continued efforts to expand its year-old Washington office in order to reach out to influential lawmakers and regulators.

Marventano — formerly Jessica Wallace — will leave Comcast Corp. after less than a year to become senior vice president for government affairs at the nation’s largest radio station owner.

She replaces Andy Levin, who has been named executive vice president and chief legal officer and will move to the company’s San Antonio headquarters.

It was not long ago that Marventano and Levin worked together as senior telecommunications counsels on the House Energy and Commerce Committee.

Marventano worked for Rep. Billy Tauzin (R-La.), chairman of the committee at the time, while Levin worked for the ranking member, Rep. John Dingell (D-Mich.).

Also at Clear Channel’s Washington office is Brendan Kelsay, another former telecom aide to Dingell.

On Capitol Hill, the three worked closely together on several telecommunications issues, most notably the Tauzin-Dingell broadband bill that passed the House but was killed in the Senate.

In her new post, Marventano also will work alongside Robert Fischer, a former aide to Senate Commerce, Science and Transportation Chairman John McCain (R-Ariz.).

Hollings Aides Leaves Hill. As Sen. Fritz Hollings (D-S.C.) nears his retirement, the inevitable exodus from his staff has begun.

Steve Hartell, a top defense aide, has become the latest Hollings aide to leave the Hill.

After starting with Hollings as a research assistance for the Senate Commerce, Science and Transportation Committee, Hartell has joined EMC, an information technology firm based in Northern Virginia.

Last month, Hollings’ state director, John Funderburk, moved to Washington to join the American Medical Association.

Also this year, Andy Davis left his position as Hollings’ spokesman on the Commerce Committee.

Davis became a press aide in Sen. John Kerry’s (D-Mass.) personal office.

Several senior Hollings aides remain, including Kevin Kayes, the minority staff director on the Commerce panel.

Hartell spent the last year as Hollings’ legislative director, specializing in appropriations, defense and homeland security work.

Hartell replaced Ashley Cooper, who left Hollings last year to join the Columbia, S.C.-based energy company SCANA.

Dine and Dash. Kristin Nolt is leaving the National Restaurant Association — and Washington — to become the head of public affairs for Disneyland Resort in Anaheim, Calif.

Nolt, a graduate of the University of Delaware, worked for then-governor and current Rep. Mike Castle (R-Del.) for seven years before joining the restaurant’s trade association in 1997.

Moore Takes on MPAA. The creator of software that allows Americans to copy DVDs came to Capitol Hill last week to urge lawmakers to approve legislation to allow folks to copy home movies and videos.

Robert Moore, the founder of 321 Studios, was in town to ask Members of Congress to consider legislation sponsored by Reps. Rick Boucher (D-Va.) and John Doolittle (R-Calif.) that would give consumers access to technology that could duplicate DVDs.

However, Moore is taking on one of Washington’s most powerful lobby, the Motion Picture Association of America.

CropLife Changes. CropLife America, the trade association for the crop protection industry, has added three new lobbyists to its Washington office.

Patrick Donnelly will take over as executive vice president and chief operating officer after working for Dow AgroServices.

Meanwhile, Rich Nolan joins the association from Ball Janik, along with Christine Robbins, a one-time aide to former California Gov. Gray Davis (R) and ex-Rep. Gary Condit (D-Calif.).
