D.C. Mayor Marion Barry's attorney tried to get Hazel Diane "Rasheeda" Moore to acknowledge yesterday that Barry declined drugs during the Vista Hotel sting seven times, and that the mayor gave her money because he thought she was buying drugs for herself.

R. Kenneth Mundy, in his second full day of questioning Moore, spent the morning walking Moore through a transcript of the Vista videotape, noting seven places where Barry declined a direct offer of drugs or showed no interest when the subject came up.

For the most part, Moore agreed with Mundy that Barry declined several times to smoke the crack, but she maintained that it was Barry who brought up the subject of drugs and that he made reference to drugs throughout the 83-minute tape.

Mundy also drew attention to the time Barry asked Moore how to use a crack pipe.

Moore countered that Barry's naivete about the pipe was bogus, that he had given her money to buy crack cocaine for himself and that the indifference to drugs that he showed on the tape was because of his wariness about using drugs in a strange place.

"Somewhere, obviously Mr. Barry's intuition was reading something to him, but he wasn't clear as to what was happening in his mind," Moore said. She also said she thought that Barry had become leery about using drugs in a strange hotel room after the so-called Ramada Inn incident, on Dec. 22, 1988.

In that incident, police responded to a report of drug activity in the Ramada Inn hotel room of Barry friend Charles Lewis, and turned away when the hotel manager learned Barry was with Lewis.

Barry "is a very intelligent man, and he has thought about how to handle himself in a hotel situation based on the Charles Lewis situation," Moore told Mundy.

"Ma'am, if that is true, if that is an explanation, why did Mr. Barry go on a few moments later and hit the pipe?" Mundy asked.

" . . . Because he had a desire to," Moore replied.

Moore denied Mundy's assertion that Barry gave her cash because he thought she was buying cocaine for herself. She testified that the money he gave her was for drugs for himself, "not for me."

By giving Moore money to buy drugs -- whether for him or for her -- Barry could be considered to have aided and abetted drug use, said Judy Smith, a spokeswoman for the U.S. Attorney's Office.

Another witness, James McWilliams, pleaded guilty to aiding and abetting cocaine possession by providing money to Lewis, who then bought drugs.

In an interview yesterday, Mundy declined to comment on whether Barry could be found guilty of aiding and abetting.

Yesterday afternoon, Mundy continued to press Moore to explain her actions in the videotape -- for instance, why she twice moved a chair in the foreground of the videotape. Moore testified earlier that she knew the room contained hidden cameras and microphones, but didn't know where they were.

Mundy replayed two parts of the videotape that showed Moore moving the chair, once to sit in it and once to move it out of the picture. The second movement came just as Barry was leaning over the crack pipe in the background.

"Miss Moore, you knew where the camera was, right?" Mundy asked.

"No, I didn't know where the camera was," she said.

"Why did you keep moving the chair?" Mundy asked.

"To be honest with you, because of the anxiety I was feeling from the operation," Moore said.

Speaking to reporters after the trial had recessed for the day, Mundy said he thought he had damaged Moore's credibilty, and that she knew where the hidden camera was.

Also yesterday, the husband of a prospective witness in the trial criticized a Washington Post report that his wife, Marcia Griffin, provided cocaine to the mayor during a period that his company was awarded more than $4 million in city contracts.

James M. Griffin, president of Comprehensive Marketing Systems Inc. and Temporary Living Communities Corp., did not mention his wife in his statement, and identified himself as the "sole owner" of both firms. City incorporation records list Marcia Griffin as an officer in both companies.

"The innuendo in the article that CMS and TLC received contracts from the city of Washington, D.C., as a result of undue or illegal influence is absolutely false," the statment said.

The Post reported that Marcia Griffin, who had a romantic relationship with Barry, has told investigators that she gave cocaine to the mayor on several occasions.

James Griffin said in his statement that his companies had received contracts in the District since 1984 to provide housing for the homeless, and "no influence, direct or indirect, was used in obtaining these contracts."

A spokesman for the House Committee on Government Operations said yesterday that the staff was reviewing James Griffin's testimony last month at a hearing on city homeless contracts. Griffin testified that he and another relative, Theodore Griffin, were the only family members associated with the shelters.

According to telephone logs of late-night and weekend calls to Barry's command center, Marcia Griffin left more than 50 message for the mayor either in her name or that of an alias, Deborah Chase, over 15 months.
