 National finance co-chair Tom Loeffler left the campaign due to his lobbying group's work for Saudi Arabia and other foreign countries.Other top campaign staff such as campaign manager Rick Davis (who devised the new rules), strategist Charles Black, and foreign policy advisor Randy Scheunemann, had already stopped such activities and remained with the campaign.McCain was criticized by Campaign Money Watch and MoveOn.org for retaining Black, but Public Citizen came to McCain's defense, saying that "Regardless of how many lobbyists are working on his campaign or raising money for him, John McCain has fought for 14 long, hard years for reforms that seriously limit lobbyists' power."
