Before Wednesday’s hearing on the attack in Benghazi, Libya, Republicans in Congress promised explosive new details about the administration’s mishandling of the episode. Instead, the hearing showed, yet again, that sober fact-finding is not their mission. Common sense and good judgment have long given way to conspiracy-mongering and a relentless effort to discredit President Obama and former Secretary of State Hillary Rodham Clinton…

The hearing did not prove anything like an administration cover-up or other hysterical allegations of crimes equal to Watergate that some Republicans, such as Representative Steve King and Senator Lindsey Graham, have alleged. Republicans have held numerous hearings and briefings on Benghazi and are threatening to hold even more. It is a level of interest they did not show during George W. Bush’s administration when there were 64 attacks on American diplomatic targets or in the years they spent cutting back diplomatic security budgets.
