In other campaign news, Senator McCain’s national finance co-chair Tom Loeffler has resigned after it was revealed his lobbying firm has collected nearly $15 million from Saudi Arabia since 2002. Loeffler is the fifth high-ranking McCain adviser to resign in recent weeks due to his lobbying ties. On Thursday, McCain’s energy adviser Eric Burgeson stepped down after it was revealed he is lobbyist on energy issues for Barbour Griffith & Rogers. Last week, two other McCain staffers resigned after acknowledging they had lobbied for the military junta in Burma. McCain’s campaign recently issued a new policy that requires all campaign personnel to either resign or sever ties with lobbying firms or outside political groups. But several prominent lobbyists retain key posts in McCain’s campaign. McCain’s campaign manager Rick Davis is on leave from the lobbying firm he has run for years. And McCain’s top political adviser Charles Black is the founder of the Washington lobbying firm Black & Associates.
