Chairman Darrell Issa called the hearing to look into allegations that security requests were denied. Ranking member Elijah Cummings told reporters Friday that "I think it's a lot about politics. Come on, this is the Oversight Committee."
House Minority Leader Nancy Pelosi has also suggested that the hearing is political in nature.
Issa and Rep. Jason Chaffetz sent a letter to Secretary of State Hillary Clinton this week, demanding answers about reports that more security was requested in Libya. Chaffetz is a Romney campaign surrogate.
Clinton has said she will cooperate with the House investigation, which comes after a Sept. 11 attack in Benghazi that left U.S. Ambassador Chris Stevens and three other Americans dead.
Cummings was about to be briefed about the Libya situation before speaking to reporters, but said he doesn't think there will be witnesses called by Democrats. He also wasn't sure how many Dems would make the hearing.
"It's kind of short notice, so we're trying to get our members here," he said. "I'll be here, live and in living color."
