The City Council’s ethics committee is scheduled to begin disciplinary hearings today on allegations that Allan Jennings Jr., a councilman from Queens, sexually harassed or created a hostile work environment for five women.

The Committee on Standards and Ethics has three closed-door hearings scheduled today through Wednesday, but will add or subtract from that depending on how many witnesses testify and how long questioning takes, said a council spokesman, Stephen Sigmund.

Mr. Jennings, a Democrat who represents parts of Jamaica, did not return calls for comment. In the past, he has called the charges “nonsense” and said they were part of a “political witch hunt.” During a brief telephone conversation Friday, his lawyer, Robert Ellis, said Mr. Jennings would not testify at the hearings. He then hung up on a reporter seeking clarification.

In June, the ethics committee recommended six charges against Mr. Jennings. Two are for alleged sexual misconduct toward an attorney for the council and a former aide, sources say. The committee also charged Mr. Jennings with creating a hostile work environment; misusing council funds by having an aide clean his apartment, and acting inappropriately toward Councilwoman Sara Gonzalez by reading her a portion of a biblical psalm.

Mr. Jennings, who has denied five of the charges, acknowledged having read the psalm to Ms. Gonzalez but said, “I don’t see how reading the Bible is inappropriate behavior.”

The staff attorney sued the council in May for allegedly ignoring her pleas after she reported that Mr. Jennings grabbed her wrist and shared detailed information about his sex life. The aide claimed Mr. Jennings fired her from the Civil Service and Labor Committee after she refused to go on a date with him.

If the ethics committee finds Mr. Jennings guilty, it can recommend that the full council impose penalties ranging from fines to expulsion. The council speaker, Gifford Miller, has been criticized for not acting fast enough after one of the alleged victims complained to him.
