As House Intelligence Committee chairman, Nunes oversaw the Republican-controlled committee's two-year-long investigation into the U.S. response to the 2012 Benghazi attack. The committee's final report found no evidence of wrongdoing on the part of Secretary of State Hillary Clinton or any other Obama administration officials, and concluded that the response of CIA and U.S. military to the attack on the U.S. diplomatic compound was correct. The committee's report debunked "a series of persistent allegations hinting at dark conspiracies" about the attack, determining that "there was no intelligence failure, no delay in sending a CIA rescue team, no missed opportunity for a military rescue, and no evidence the CIA was covertly shipping arms from Libya to Syria", but found "that the State Department facility where Stevens and [Sean Smith were killed was not well-protected, and that State Department security agents knew they could not defend it from a well-armed attack".
