Republican Rep. Darrell Issa said in a statement and letter to Secretary of State John Kerry on Monday that delays in scheduling interviews with the officials were taking too long and he had no choice.
Four Americans, including Ambassador Chris Stevens, died in the Sept. 11, 2012, attack. Republicans have accused the Obama administration of misleading the public about the cause of the attack, playing down terrorism in the heat of the presidential election.
Issa issued subpoenas for officials involved in diplomatic security.
Democrats have criticized the House Republican efforts as politically motivated.
