Los Angeles, San Francisco, Washington D.C. and Boston are cities on the United States Olympic Committee's short list of potential 2024 Summer Olympics hosts.
The USOC will figure out by next year if it will advance an Olympic bid by a US city. The winning US entry, if there is one, would then compete with bids from around the world.
The International Olympic Committee will choose the host of the 2024 games in 2017.
