Donald E. Campbell, one of the original Watergate prosecutors, has left the U.S. attorney's office here after 14 years to become general counsel to the federal Office of Government Ethics.

Campbell, one-time chief of major crimes in the prosecutor's shop, now will be chiefly responsible for reviewing the financial disclosures of top government appointees, among other duties.

Many saw Campbell as one of the victims of a major reorganization of the prosecutor's office under U.S. Attorney Joseph E. deGenova that absorbed the major crimes operation in an expanded criminal section, with William S. Block as chief and Campbell designated one of four "senior" attorneys.

"I have no complaints about what happened," said Campbell of the move. "It was time for me to leave and do something different."

Another alumnus of the Watergate prosecution, George Frampton, who more recently helped investigate Attorney General-designate Edwin Messe III, has taken a leave from Rogovin, Huge & Lenzner to teach law at Duke University. Partner Terry Lenzner says Frampton is considering leaving permanently to don teacher's robes.

Meanwhile, Rogovin, Huge has started a separate investigative firm out of Washington and New York with former newspaper reporters James Mintz and John Hanrahan.
