Another attendee at the meeting is heard saying: "There you go. I'm sick of it" – and Mr Winters appears to nod his head in agreement.
Ms Bryant sat still drenched and in disbelief as a woman yells, "Oh, that's classy!"
It's believed Mrs Winters was angered by a post on the reporter's Facebook page that had insinuated her husband had misused county funds for his own benefit.
Ms Bryant shared a message online she had received from someone claiming to work with Mrs Winters.
"Did you know that Jason Winters just returned from a trip to Paris?" the post read.
"After all he has not done for our county I find it ridiculous that he can afford fancy trips."
Local high school teacher Laura Arden was at the meeting and described the attack as "the most classless act I have ever witnessed in my whole life", according to a news report from WTVC NewsChannel 9.
"I looked just in time to see her dump it right on Casey's head," she said.
"And Casey just sat there. In fact, we were all shocked."
Despite the number of witnesses attending the meeting, Mrs Winters has claimed she "accidentally" poured the drink on the reporter's head "after stumbling/tripping near her", according to a local police report.
The commissioner's wife has been charged with simple battery and disorderly conduct.
Her husband, who has been criticised for excessive tax hikes, also claimed the attack was an accident but also said Ms Bryant "deserved what happened to her", according to WZQZ.
AllOnGeorgia owner Delvis Dutton slammed the incident in a statement released last week.
"What happened at the budget meeting was completely inappropriate, and I'm disappointed to see not only the behaviour of those involved but the excuses made for the behaviour after the fact," he said.
"The media plays an integral role in ensuring transparency, and these types of antics are dangerous to open government and a disservice to the people it serves."
