Recent polls show Warnock in a tight race with both Loeffler and U.S. Rep. Doug Collins, her most formidable Republican challenger. Several have also shown Lieberman within striking distance.
Warnock turned heads in April when he out-raised Collins and Loeffler in the first quarter. Both Republicans have yet to report their latest figures, though Loeffler is expected to add another $5 million to the $10 million she's pumped into her campaign.
The pastor has presented himself to voters as a candidate who can seize the "moral moment" in Washington by championing expanded voting rights, an overhaul of the criminal justice system and other progressive policies.
Collins and Loeffler have largely focused on one another rather than the Democratic side of the contest. An exception came this week when Loeffler tried to tie Warnock to the "defund police" movement that's gained traction amid protests for racial justice. The Democrat said he opposes efforts to abolish police agencies.
In Georgia's other U.S. Senate race, Democrat Jon Ossoff said this week he raised more than $2.3 million since winning the June primary to challenge Republican David Perdue, and that he took in at least $3.45 million during the April-June quarter.
Ossoff also joined the chorus of Democrats who back Warnock by formally endorsing his campaign.
Perdue, who reported in April he had roughly $9 million in his campaign account, has yet to report his latest figures.
