After Los Angeles and Paris laid out their Olympic hosting plans on Tuesday, their mayors said they could work together on a deal to ensure both cities host a Summer Games soon.
Both cities used 45 minutes of videos and speeches, including French President Emmanuel Macron promoting the Paris cause, in a closed-door session with International Olympic Committee members to explain how they would host the 2024 Olympics.
Those members should vote later on Tuesday to add the 2028 hosting rights and make both cities winners when the IOC next meets in September.
That will likely need IOC leaders to broker a consensus deal within weeks in talks which start with Paris widely seen as the 2024 favorite.
"We look forward to working together maybe not in competition but collaboration with Paris," LA mayor Eric Garcetti said at a news conference after his city's bid officials opened the campaign event.
Garcetti and Paris mayor Anne Hidalgo have long touted their good working relations on other issues such as climate change.
Minutes after Macron spoke, US President Donald Trump wrote on Twitter: "Working hard to get the Olympics for the United States (L.A.). Stay tuned!"
Still, it could be a 2028 Olympics in LA that will be the first American-hosted games since 1996 in Atlanta.
IOC president Thomas Bach Bach has said the idea of a double award was presented to him at a lunch last year by friends whom he declined to identify in a recent interview with French sports daily L'Equipe.
The LA bid team declined to comment on Tuesday whether the suggestion came from its supporters.
If Tuesday's vote passes as expected, the Bach-chaired IOC executive board could be empowered to broker a future deal on picking the 2024 host ahead of a September 13 meeting in Lima, Peru.
