Boston's bid to host the 2024 Olympics is over.

A person familiar with the decision told The Associated Press on Monday that the U.S. Olympic Committee has severed ties with Boston. The person spoke on condition of anonymity because the decision had not yet been made public.

The Boston bid soured within days of its beginning in January, beset by poor communication, low public support and an active opposition group.

The USOC board decided via teleconference after Boston Mayor Marty Walsh announced he would not be pressured into signing the host city contract that puts the city on the hook for any cost overruns.

The deadline to officially nominate a city is Sept. 15. If the USOC wants to stay in the race, Los Angeles would be its likely choice.

Now that Boston is out of the picture, the USOC wants to explore other opportunities to host the 2024 Games.

In a statement Monday announcing the end of the bid in Boston, USOC CEO Scott Blackmun said the federation was still interested in mounting a bid for the Summer Games.

He didn't mention any city specifically, though the best bet is Los Angeles would be the candidate.

L.A. Mayor Eric Garcetti released a statement saying that his office hadn't had any recent conversations with the USOC but he'd be happy to have them.

The official deadline for the USOC to submit a candidate city is Sept. 15.
