A congressional inquiry finds that the American Red Cross stonewalled lawmakers as they sought to understand the charity's finances, and that it sent significantly less money to Haiti than claimed.

The American Red Cross allegedly did not fully cooperate with a government investigation of its performance and finances. Now investigators and a congressman want the charity's books open for audits.

Reports obtained by NPR and ProPublica show the Red Cross did not monitor many of the earthquake relief projects it funded. So the agency may not have answers to this week's questions from Congress.
