“No comment,” said newly elected council member Vincent Orange, an at-large Democrat who barely broke stride while retreating from a reporter in the John A. Wilson Building lobby.

A representative for council member Yvette Alexander said the Ward 7 Democrat, who had a fundraiser hosted for her last year by the local lottery partner, “will review the situation before she comments.”

Council member Harry Thomas Jr., Ward 5 Democrat and an ally of Ms. Alexander’s and Mr. Brown’s who is under federal investigation and recently agreed to refund more than $300,000 he raised to promote youth sports, said he hadn’t formulated any thoughts on the lottery contract.

Asked whether he had concerns about the inspector general, he replied, “It’s not something I’m interested in.”

Earlier this week, Mr. Evans said that, like Mr. Wells, he has not taken a position for or against online poker. But he is sure of one thing, he said: “It should have been introduced as a free-standing bill; then we would have had the necessary hearings. Since that’s not what happened, we’re trying to play catch-up by holding hearings after the fact.”

Mr. Evans did not, however, commit to a review of the inspector general, which he said falls to the government operations committee chaired by Ms. Bowser.

The inspector general was criticized this week after Mr. Gragan told The Times that he and Mr. Nickles saw “anomalies” in the lottery contract that he has not seen in 18 years as a procurement officer but that he had no indication if an investigation was begun.

“This is shocking,” said Mr. Nickles, adding that while still in office he provided leads to the inspector general and was personally assured of an expedited and thorough investigation. “If the inspector general has not interviewed the people whose names I provided, then he ought to be fired.”
