Clinton campaign chief strategist Mark "Pig" Penn has resigned his position in the campaign, according to CNN. Last week, Penn acknowledged meeting with Colombian officials to discuss a free trade agreement with the U.S that his company, Burson-Marsteller International, was lobbying Congress for. Unfortunately, Sen. Clinton opposes the agreement, and Penn didn't really make it clear to the Colombians that he wasn't representing Clinton. The Colombians also dropped Burson-Marsteller after the flap.
Penn is extremely unpopular within the Clinton campaign, and is known to have had frequent shouting matches with her senior team. Many Clinton insiders blame him for the failure to plan for primaries after super Tuesday and for his inept spinning to the press. You can be sure they are planning a big farewell party, but won't be inviting him.
