The political director for the Georgia Trial Lawyers Association announced his resignation last week in a letter warning the group’s leaders that they were making ”an all-but-fatal decision” in promoting the head of GTLA’s political action committee to run the whole organization.

Addressing the GTLA’s 48-member executive committee, Clark wrote that he disagreed with a decision to elevate Caroline McLean to a new CEO post that would, among other things, oversee Clark’s running of the group’s political and legislative operation. McLean has headed the GTLA’s Civil Justice PAC since 2013. Clark has been at the organization since 2002.
