President-elect Joe Biden will campaign in Atlanta on Tuesday for Jon Ossoff and Raphael Warnock to rally Democrats ahead of Jan. 5 runoffs to determine control of the U.S. Senate.

The event coincides with the first week of early voting in the twin contests — and comes a day after presidential electors in Georgia and other states formally cast their votes to make Biden the next president. Details of the Atlanta rally have yet to be announced.

Biden’s trip will follow a string of high-profile Republicans who have stumped for U.S. Sens. Kelly Loeffler and David Perdue. A half-dozen potential 2024 GOP presidential candidates have already campaigned in Georgia, and Vice President Mike Pence rallied Thursday in Augusta for his third visit to Georgia this month.

President Donald Trump drew thousands to Valdosta on Saturday evening, where he urged his loyal supporters to vote for the GOP candidates even as he aired his unfounded grievances about a “rigged” election and blasted state officials for refusing his calls to illegally overturn the election results.
