It was incorrectly reported Thursday that Annette Samuels, former press secretary to D.C. Mayor Marion Barry, delivered materials to a federal grand jury Wednesday. Samuels did not deliver materials when she appeared before the panel. (Published 6/28/87)

Annette Samuels, Mayor Marion Barry's former press secretary, and Anita Bonds, his 1986 campaign manager, testified yesterday before a federal grand jury investigating D.C. contracting.

Samuels, who left the press secretary's job in May after serving as Barry's chief spokeswoman for more than five years, appeared before the grand jury about 30 minutes and did not comment to reporters as she left the U.S. District Courthouse.

She apparently delivered a box of materials to the grand jury, and while before the body was questioned by Assistant U.S. Attorney Daniel Bernstein, the main prosecutor in the investigation of city contracts. Samuels was not accompanied by a lawyer.

Bonds, who is now a special assistant to the mayor, spent nearly two hours testifying before the grand jury and also declined to talk to reporters. She was accompanied by Eric Washington, a special assistant to Corporation Counsel Frederick D. Cooke Jr.

Neither Samuels nor Bonds could be reached for comment last night.

Samuels is a former press aide to President Jimmy Carter and worked as Barry's press secretary from 1981 until her resignation last month. Samuels has taken a leave of absence from the District government to attend the John F. Kennedy School of Government at Harvard University.

Bonds is a longtime political activist in Washington and adviser to Barry. She served as his deputy campaign manager in 1982 and played a leading role in his initial campaign for mayor in 1978.

In another development yesterday, it was learned that six more subpoenas were issued to the District government for what were termed "very specific" documents. Washington declined to say which city agencies received the subpoenas.

Also appearing at U.S. District Court yesterday was John B. Clyburn, a D.C. businessman who is a central figure in the contract probe. Clyburn attended a hearing concerning his $25 million libel suit against The Washington Times newspaper.

The hearing before U.S. District Judge Norma Holloway Johnson was to determine whether the newspaper will have to disclose confidential sources it used in the preparation of stories published in April 1986 concerning the 1983 death of Joann T. Medina, a friend of Clyburn's.
