House Democrats, meanwhile, outlined plans Monday for a vote later this week to formalize impeachment procedures. House Rules Committee Chairman Jim McGovern said the Thursday vote would “ensure transparency and provide a clear path forward” for the inquiry.

Carr, a Republican, is a former top aide to Isakson who was appointed to the Attorney General's office in 2016. He narrowly won a full term in last year's midterm election with vows to crack down on gang crimes and defend conservative initiatives in court.

He is considered a potential candidate to succeed Isakson, who is stepping down at the end of the year, but he has yet to formally apply for the job with Gov. Brian Kemp's office and isn't actively maneuvering for it.

Kemp, too, has forcefully condemned the impeachment effort. He told an Athens crowd that the process was a "big waste of time" and that Democrats should focus their attention on an immigration overhaul and new trade agreements.
