President Donald Trump tweeted that he is 'working hard' to bring the Olympics to Los Angeles, as L.A. mayor Eric Garcetti and French President Emmanuel Macron pitched plans to host the games.

'Working hard to get the Olympics for the United States (L.A.). Stay tuned!' Trump tweeted Tuesday morning, when he also shot out missives about health care, a Marine plane crash, ISIS, and presidential nominations.

Trump's tweet game after Garcetti and Macron – who Trump is to meet this week when he flies to Paris for Bastille Day – spoke about a possible deal that would make both winners of upcoming summer games.

They International Olympic Committee votes later Tuesday on the coveted hosting rights, following spiraling costs at Olympics hosted in Sochi and Rio.

In 2009, President Barack Obama made a high-profile and unsuccessful effort to bring the games to Chicago, jetting to Copenhagen and deploying First Lady Michelle Obama in the lobbying effort to win Olympic glory for his home town.

On his return, Obama said without regret that it is 'always a worthwhile endeavor to promote and boost the United States.'

'One of the things that I think is most valuable about sports is that you can play a great game and still not win,' Obama said at the time.

Los Angeles and Paris both used 45 minutes of videos and speeches to a closed-door session with International Olympic Committee members to explain how they would host the 2024 Olympics.

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,' 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.

A recent report on ESPN.com cast the dual-win scenario as the culmination of a tireless process put forward by Garcetti and Hidalgo.

'Usually you have five plazas around the world, four crying and one celebrating,' Garcetti told the sports network in June. 'This is going to be a slow dual win. The IOC will make an announcement that they are going to move forward with dual bids and then we will know we've won. Both of us.'

President Barack Obama and first lady Michelle Obama arrive for Chicago's final bid presentation at the Bella Center in Copenhagen, Denmark, Friday, October 2, 2009, for selection as the host city for the 2016 Summer Olympic Games

Standing in front of a backdrop of the Chicago skyline, US first lady Michelle Obama speaks in support of Chicago hosting the 2016 Summer Olympics, on September 30, 2009, in Copenhagen. Michelle Obama joined the Chicago 2016 bid team competing with Tokyo, Madrid, and Rio de Janeiro for the right to host the 2016 Summer Olympic Games

According to the report, 'It has been a bid campaign like no other, featuring two forceful, dynamic personalities 5,642 miles apart: Garcetti, fueled by a lifelong desire to bring the Games back to his hometown, and Hidalgo, a late convert who now sees the event as a way to throttle up positive change. Both have made themselves indispensable in lobbying other politicians, the public and Olympic sports officials.'

'We are all at the disposition and by the side of the IOC which was right to ask itself this question,' Hidaldo said at the Paris news conference, citing her friendship with Garcetti as potentially a 'key element' to reaching an agreement.

The dual award can give the IOC a decade of stability with two world-class cities touting financially secure bids with, in LA's case, zero risk of white elephant venues. This follows years of overspending by Olympic hosts and political defeats to sink potential candidates.

The win-win option also guards against a 2024 loser refusing to bid again for 2028m and avoids inflicting a third recent defeat on Paris - which lost with bids for the 2008 and 2012 Olympics - and the United States. New York and Chicago both lost heavily for 2012 and 2016, respectively. Paris also failed with a 1992 bid.

'We lost three times, we don't want to lose a fourth one,' Macron said. 'I'm here to convey the message that there's a strong unity to back this candidacy.'

Garcetti said the Olympic movement 'can't afford to lose the United States.'

'Both of us will find it more and more difficult to convince cities - whether it's Paris, Los Angeles or other American cities - to really go into this process if one of us gets turned down,' the mayor said.

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 Tuesday whether the suggestion came from its supporters.

'He (Bach) has good friends who gave him good advice,' LA bid chairman Casey Wasserman said.

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 Sept. 13 meeting in Lima, Peru.
