Final answer:
The congressional investigation into Hurricane Katrina found issues with leadership, preparedness, and communication, but not with foreign aid. Criticisms targeted FEMA and the Bush administration for their inadequate response.
Step-by-step explanation:
The congressional investigation of the government’s response to Hurricane Katrina identified problems in several key areas; however, foreign aid was not one of these areas. The investigation found significant issues concerning leadership, preparedness, and communication, which hindered the response efforts. As documented in the aftermath of Katrina, there were major failures in leadership, with FEMA and the Bush administration coming under heavy criticism for their lack of preparedness and inadequate response. Additionally, communications were critically lacking among federal, state, and local agencies, as well as with the public, further complicating the rescue and relief efforts. The poor execution of evacuation plans and the slow response to the crisis particularly highlighted these deficiencies, leaving vulnerable populations such as poor African Americans to suffer the most.
