John McCain's national finance co-chairman has resigned because of ties to lobbyists.
Former Texas Congressman Thomas Loeffler resigned after the campaign instructed staff last week to disclose all lobbying ties and to make certain they are no longer registered as lobbyists or foreign agents.
Loeffler lobbies for the European Aeronautic Defence and Space Company, which with Northrop Grumman won a lucrative contract to provide air refueling tankers for the Air Force. McCain helped scuttle an earlier contract that would've gone to a competitor.
Past lobbying work does not automatically disqualify someone from working for McCain's campaign. But McCain is seeking not only to comply with laws but also to live up to a higher standard to help showcase his image as a reformer of money in politics.
