BOSTON — The United States Olympic Committee killed Boston’s beleaguered bid for the 2024 Summer Olympics on Monday, hours after Mayor Martin J. Walsh said that he would not sign a contract with the organization if it wanted him to do so by the end of the day.
The U.S.O.C. announced the termination of the bid in a statement, saying support for the Boston bid was not strong enough. The group said it would consider other options for a 2024 bid.
“I cannot commit to putting the taxpayers at risk,” Mr. Walsh had said at a hastily called news conference.
