RIO DE JANEIRO - The International Olympic Committee cracked down on the four host cities hoping to land the 2024 Olympic Games on Wednesday for breaking bidding rules by lobbying the media in Rio.
Budapest, Los Angeles, Paris and Rome are in the running for the Games with a final decision to be taken in Lima, Peru in September next year.
"Three 2024 Candidate Cities have contacted media and invited them to their hospitality houses here in Rio. They have all been reminded that this was not permitted and have subsequently stopped their activities," the IOC said in a statement.
The hopeful candidates have promised to be on their best behaviour for the rest of the Rio Games.
"The IOC sent an email reminder to us and other bid cities of the Rio restrictions, which we surely will observe," said a spokesperson for the Los Angeles team.
"We got this notice from the IOC to remind us not to do some kind of promotion on the bid," added a spokesperson Rome's bid.
"We cannot invite media on behalf of Roma 2024. We will fully comply to the recommendations of IOC."
All four bids have used the exposure of Rio to further their candidacy.
French president Francois Hollande showed his support for the Parisian bid in a press conference before the start of the Games and met IOC president Thomas Bach on a two-day visit to Brazil.
Italian Prime Minister Matteo Renzi, Hungarian president and Prime Minister Janos Ader and Viktor Orban, and US Secretary of State John Kerry have also been in Rio.
