1. The House Oversight and Government Reform Committee's investigation into the United States Department of Veterans Affairs (VA)
The House Oversight and Government Reform Committee launched an investigation into the VA in 2014 after reports of widespread delays in veterans' care. The committee held a series of hearings and issued a report in 2015 that found that the VA had failed to provide timely and adequate care to veterans. The report also found that the VA had engaged in a number of deceptive practices, such as falsifying wait time records.
As a result of the committee's investigation, the VA implemented a number of reforms, including firing several senior officials and creating a new system for tracking wait times. The VA also increased funding for veterans' care.
2. The Senate Intelligence Committee's investigation into the Central Intelligence Agency's (CIA) use of torture
The Senate Intelligence Committee launched an investigation into the CIA's use of torture in 2009. The committee's report, which was released in 2014, found that the CIA had used torture on a number of detainees, including waterboarding, sleep deprivation, and stress positions. The report also found that the CIA had failed to properly document its use of torture, and that it had misled Congress about the effectiveness of torture.
The committee's report was highly critical of the CIA, and it led to a number of reforms at the agency. The CIA ended its use of waterboarding and other harsh interrogation techniques, and it created a new oversight board to review the agency's use of force.
Both of these investigations were examples of effective Congressional oversight. The committees were able to uncover serious problems at the VA and the CIA, and they forced the agencies to make changes. These investigations also helped to restore public confidence in these agencies.
It is important to note that these investigations were not partisan. Both the House Oversight and Government Reform Committee and the Senate Intelligence Committee were bipartisan, and they were led by members of both parties. This helped to ensure that the investigations were fair and impartial.
