国际奥委会将同时宣布2024和2028年的奥运主办城市

The International Olympic Committee Tuesday has decided to award the 2024 and 2028 Summer Olympic Games in the same session, in a move that would effectively guarantee that Paris and Los Angeles will be the winners.

The two cities have been lobbying heavily to host the international sporting event.

The French capital last hosted the games in 1924. Los Angeles did so back in 1984.

In a tweet Tuesday, U.S. President Donald Trump said, "Working hard to get the Olympics for the United States (L.A.). Stay tuned!"

The winning bids will be announced on September 13 in Lima, Peru.

The Olympic movement has had trouble attracting prospective hosts because of the amount of money involved.
