MOUNT PLEASANT, S.C. (AP) -- Republican Fred Thompson played down a staff member's departure and a New Hampshire supporter's defection today.
The former Tennessee senator said it's not up to him to know what's going on at every level of his presidential campaign.
Thompson's campaign recently lost Nelson Warfield, a political media strategist, and New Hampshire Republican Dan Hughes said he had switched to John McCain's team.
Thompson is making his second trip through South Carolina today as a presidential candidate.
Thompson said fund raising and polls show that his campaign is meeting expectations.
