Hillary Clinton the former secretary of state, having just officially launched her second campaign for the presidency, practically begged the Republican chairman of the House Select Committee on Benghazi, Representative Trey Gowdy of South Carolina, to allow her to testify in public. Gowdy wants to question her about the 2012 terrorist attack and her much-criticized decision to use a personal email server during her tenure at the State Department and then to wipe it clean after leaving office. Yet in an equally puzzling move, Gowdy initially said no: He demanded that Clinton first come in for a private interview about the emails, an arrangement that he said would, among other things, "best protect the secretary's privacy."
