A month after Hurricane Maria hit Puerto Rico, Army Lt. Gen. Jeffrey Buchanan stepped off a helicopter in the town of Ceiba with a mission: Get relief supplies to people in need.

Before Hurricane Maria hit last September, Puerto Rico was battered by the forces of another storm — a financial storm.

The island's own government borrowed billions of dollars to pay its bills, a practice that Puerto Rico's current governor, Ricardo Rosselló, now calls "a big Ponzi scheme."

Pearlie Mae Brown's wooden house is listing a little. The screen door is broken, and another screen door is nailed sideways over a window.

An $8 billion federal program to build housing for the poor is so lacking oversight that virtually no one in government knows how it is working, a government auditor testified before Congress today.

"IRS and no one else in the federal government really has an idea of what's going on," said Daniel Garcia-Diaz, an auditor with the Government Accountability Office while testifying before the U.S. Senate Committee on Finance. "These are basic accountability requirements we would expect of any program, especially one as important as this one."

On the south side of Dallas, Nena Eldridge lives in a sparse but spotless bungalow on a dusty lot. At $550 each month, her rent is just about the cheapest she could find in the city.

After an injury left her unable to work, the only income she receives is a $780 monthly disability check. So she has to make tough financial choices, like living without running water.

A new report by the New York attorney general's office finds that a lack of accountability in the nation's flood insurance program is costing taxpayers millions. The office also announced 50 felony charges against an engineering firm for allegedly writing fraudulent reports in the aftermath of Superstorm Sandy.

The American Red Cross spent a quarter of the money people donated after the 2010 Haiti earthquake — or almost $125 million — on its own internal expenses, far more than the charity previously had disclosed, according to a report released Thursday by Iowa Sen. Chuck Grassley.

The report also says the charity's top officials stonewalled congressional investigators and released incomplete information about its Haiti program to the public. It concludes "there are substantial and fundamental concerns about [the Red Cross] as an organization."

On a cold rainy day last fall, dozens of people gathered in a plaza across the street from New Jersey's state Capitol. They held press conferences and slept overnight in lawn chairs.

The American Red Cross, which has often boasted of its transparency, attempted last year to halt a congressional inquiry into its disaster relief work, according to a private letter Red Cross CEO Gail McGovern wrote to Rep. Bennie Thompson.

The American Red Cross is under pressure this week to answer detailed questions from Congress about how it spent the nearly half-billion dollars it raised after the 2010 earthquake in Haiti.

Some of those answers might be difficult to come by. New documents obtained by NPR and ProPublica reveal that the Red Cross may not have an accurate accounting of how all the money was spent.
