LAUSANNE, Switzerland (AP) — Los Angeles and Paris have laid out their Olympic hosting plans to the IOC.

Following their pitches, the two cities' 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 today 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. That would be exactly 100 years after Paris last hosted the Olympics.
