Boston, Los Angeles, San Francisco and Washington are the cities still in the running for a possible U.S. bid to host the 2024 Summer Olympics.
A process that began 16 months ago when the USOC sent letters to leaders in 35 cities is now at four finalists after Dallas and San Diego were scratched from the list. Los Angeles hosted the 1932 and 1984 Olympics. The other three cities would be first-time hosts.
The International Olympic Committee will award the Games in 2017.
The last two U.S. candidates both suffered humiliating fourth-place finishes: New York for the 2012 Olympics and Chicago for the 2016 Games that went to Rio de Janeiro.
