Lawson added that, "out of an abundance of caution, (Loeffler) will continue to self-isolate and be retested again to hopefully receive consecutive negative test results".
On Sunday, Loeffler campaign spokesperson Stephen Lawson said that Loeffler was cleared for campaigning after rapid test results were negative for COVID-19.
A test Saturday came back inconclusive and Sunday's test came back negative, Loeffler's campaign said.
"I pray that her test results come back negative and that she is back on the campaign trail soon", he said.

Republican candidate for U.S. Senate, Sen.
Loeffler is now campaigning in a high-stakes race that could determine control of the Senate. David Perdue, who is also up for election in the runoff.
Loeffler appeared at a campaign event with Vice President Mike Pence and Sen.

Loeffler is running against Democrat Raphael Warnock and Perdue faces Democrat Jon Ossoff. Democrats would need to win both runoff races to have an equal number of seats, 50, with Vice President-elect Kamala Harris as the tie-breaking vote.
Mr. Warnock wished Ms. Loeffler well on Twitter.
In twin statements, Perdue and Loeffler said they supported Trump's recount demands. Both have followed the president's lead in making unsubstantiated claims of voter fraud in order to energize their base, even calling on Georgia's Republican secretary of state to resign. Every legal vote should be counted for Donald Trump.
Neither Perdue nor Loeffler has detailed what they think Raffensperger did wrong, although they want election officials to re-examine the signatures on envelopes of mailed-in absentee ballots, a move Raffensperger says is pointless because the ballots can not be traced back to envelopes once separated.More news: Los Angeles dining ban will move forward despite effort to block measure
