The Georgia Republican Party filed a complaint Sunday with the Federal Election Commission alleging the campaign of Georgia Democratic candidate Jon Ossoff is coordinating its message with a newly formed Majority PAC, The Georgia Way.

Ossoff is challenging Republican incumbent Sen. David Perdue in one of two Senate runoffs on Jan. 5 after no candidate picked up a majority of votes during the Nov. 3 election. Democrat Raphael Warnock is facing off against Republican incumbent Sen. Kelly Loeffler in the other race.
