(CNN) - Republican members of Congress plan a host of questions for Secretary of State Hillary Clinton during her long-awaited testimony on Wednesday about the deadly attack on the U.S. diplomatic compound in Benghazi, Libya.
Questions are expected to range from a security vacuum in Northern Africa to new cables suggesting that Ambassador Christopher Stevens, who was killed in the September 11 assault, once proposed moving the compound to a more secure location adjacent the CIA Annex, sources tell CNN.
