The U.S. Olympic Committee has ended Boston's bid to host the 2024 Summer Olympics Monday afternoon. The committee spent months trying to persuade the people of Boston that the Summer Games would be good for the city, but officially threw in the towel over concerns over taxes, according to the New York Times.

The CEO of U.S.O.S. Scott Blackmun gave a statement on Monday. "The U.S.O.C. does not think the level of support enjoyed by Boston's bid would allow it to prevail over great bids from Paris, Rome, Hamburg, Budapest or Toronto," he said, according to WBUR.

The decision from the U.S.O.C. came hours after Mayor Martin J. Walsh announced he wouldn't sign a host city contract with the U.S.O.C. without more support from the people of Boston, according to WBUR News.

"I refuse to mortgage the future of the city away," said Mayor Walsh, according to the New York Times. "This is a commitment that I can't make without ensuring the city and its residents will be protected."

The chairmen of No Boston Olympics released a statement later in the day.

"We need to move forward as a city, and today's decision allows us to do that on our own terms, not the terms of the U.S.O.C. or the I.O.C.," they said, according to the Associated Press.

From the start, Boston's bid for the Olympic Games was full of controversy. There was active opposition throughout the city and a constant struggle to win support, according to the AP.

Hope still lingers that the U.S will host the Summer Games, focus now moving to Los Angeles in the next seven weeks that are left to make the bid official.
