Fed up with a collapsing economy, Venezuelans have been turning out in huge numbers this week to support a referendum that could potentially end the rule of President Nicolas Maduro and his Socialist Party.

The opposition has to collect hundreds of thousands of signatures as the first step in a complicated process leading to a recall vote on ousting Maduro. The electoral authority gave the opposition five days to verify the signatures. The deadline is Friday, and it's a race against time for both the opposition and the president.

Guanabara Bay, where the Olympic sailing competition will be held this coming August, is a place of striking views — and filthy water that hides some nasty secrets.

Many sailors have complained about the pollution and debris in the water where they will be racing. For Brazilians whose jobs depend on the bay, it's a long-term problem that's only getting worse.

Alexandre Anderson, who heads the region's largest fishermen's association, took me out onto the water to show me the extent of Rio de Janeiro's water crisis.

In an Olympic first, 10 members of an unusual team will be competing at the Summer Games in Rio de Janeiro: a squad made up entirely of refugees.

Those who made the cut include Popole Misenga and Yolande Mabika, two refugees from the Democratic Republic of Congo. They are already living in Brazil, where the games open on Aug. 5.

In the misty rain, surrounded by Rio de Janeiro's green hills, police officer Eduardo Dias was buried last week. He was shot, purportedly by gang members, as he was leaving his post inside the favela, or shantytown, where he worked as a community cop.

The killing took place a few hundred feet from the Maracana Stadium, where the opening ceremony of the Summer Olympics will be held on Aug. 5. As family members wept by the graveside, the pastor raised his hands.

Three years ago, NPR visited the port of Suape outside the northern Brazilian city of Recife when it was an example of Brazil's booming economy. Brazil's state oil company, Petrobras, has a large refinery that was working full tilt.

He asked for $7 million to fight Zika.

He got a few hundred thousand dollars.

That's the story that Jailson Correia tells. He's the health secretary for Recife, the city with the most cases of brain damage in infants linked to Zika. The virus began sweeping through Brazil last fall. In November, concerned about the scope of the outbreak, he asked the federal government for help. What they gave was a drop in the bucket.

The biggest party in Brazilian President Dilma Rousseff's coalition has pulled out, severely wounding her government and pushing her one step closer to removal. The Brazilian Democratic Movement Party, or PMDB, held a short three-minute meeting that was broadcast live on television. After the vote was taken, legislators began singing the national anthem and shouted "PT out" — Rousseff is from the PT or Worker's Party.

Reaction to the news was swift in a politically polarized country where huge demonstrations both against and for the government have taken place in recent weeks.
