It is not "all over the internet" but I did find a couple of reports about an organization that Abrams founded in 2014 and that Warnock headed up in 2019. It seems there were a few attempts at fraud under his watch. However, Abrams is not under investigation, and all of the alleged fraud adds up to maybe 3,000 votes total. That doesn't mean that those involved get a pass, just that in the whole picture, it doesn't amount to much. For future reference: when you make a claim, the burden of proof is yours. Snarky comments like "Can you use google" are for those too lazy to do their own homework.
