The commission tasked with investigating last year's terror attack on the US Consulate in Benghazi, Libya did not hold senior officials accountable.
That's the finding in a new report from the house oversight committee.
It's raising new questions about the amount of time the accountability review board took to investigate the attack that killed four people.
The committee also says that the board lacked independence.
That board was launched by then-Secretary of State Hillary Clinton and criticized the state department for failing to have sufficient security.
It also singled out mid-level officials.
The state department responded to the house committee's report, accusing it of "twisting the facts to advance a political agenda."
