The countdown is on -- 100 days until the Olympics begin in Rio de Janeiro. Here's where things stand as Brazil prepares to host the games:
The first ever Olympic Games in South America are just around the corner. However, while excitement is building, Brazil is also facing myriad problems, which could impact the games.
Brazil is in the midst of a economic and political crisis. President Dilma Rousseff is facing impeachment for allegedly breaking fiscal rules in her management of the federal budget. The turmoil is creating uncomfortable questions related the Olympics, such as who will inaugurate the games when they kick off in August.
Brazil is facing its worst recession since the 1930s. The crisis has led the government to sharply cut its security budget for the Games, creating concern about safety. Authorities say they have a good plan in place and security won't be an issue.
In terms of construction, Rio de Janeiro is very close to being ready to host the Summer Olympic Games. However, there are many concerns about how well venues were built. A bike lane, built as a beautification project for the Games, recently collapsed, killing two people.
An Associated Press investigation the last year has found alarmingly high levels of viruses and bacteria in bodies of water where athletes are set to compete.
