D.C. contractor Roy Littlejohn said in a statement issued by his attorney yesterday that he has not acknowledged giving money to convicted cocaine dealer Karen K. Johnson.

Sources have told The Washington Post that Littlejohn has acknowledged giving funds to Johnson through D.C. businessman John B. Clyburn. Littlejohn and Clyburn, the sources have said, say that their actions had nothing to do with Johnson's refusal to testify before a federal grand jury three years ago. That grand jury was investigating allegations of drug use by Mayor Marion Barry and others.

"On Aug. 14, 1987, The Washington Post stated that my client, Mr. Roy Littlejohn, 'acknowledged' giving money to Karen Johnson," attorney Eugene M. Propper said in a statement. "Mr. Littlejohn denies that he acknowledged that allegation.

"In this connection, it should be noted that Mr. Littlejohn has never been interviewed by the FBI or the U.S. attorney's office and has never been called to testify before any grand jury regarding this issue.

"Finally, he has not granted any interviews with the media or other parties regarding this matter and he will continue to maintain that position."

The Post's story, quoting the unnamed sources, said that Clyburn gave money to Johnson directly and that Littlejohn gave Clyburn money for Johnson at Clyburn's request, but did not have any personal contact with Johnson. The story said Clyburn described Johnson to Littlejohn as a friend in need and Littlejohn contributed money out of sympathy for Johnson's financial plight after she had been imprisoned for contempt of court and possession and sale of cocaine.

Sources have said that Johnson has told prosecutors that she received between $20,000 and $25,000 in exchange for her silence. According to the sources, Johnson has said she received money from Clyburn and that she believes Littlejohn also contributed funds.
