U.S. Rep. Doug Collins will report more than $2.2 million in his campaign bank account as he gears up to challenge U.S. Sen. Kelly Loeffler in a November special election.

The four-term Republican congressman raised more than $840,000 in roughly two months since entering the campaign. He transferred another $1.65 million from his U.S. House account, which also collected roughly $250,000 during the first quarter.

He can expect reinforcements. The pro-Trump Great America PAC said this week it is siding with Collins and plans to spend some of the cash it has amassed to boost his campaign.

Collins is one of 20 candidates competing against Loeffler, a financial executive who has pledged to spend at least $20 million to keep her seat.

They will share the same November special election ballot, and a runoff between the two top contenders is necessary if none get a majority of the vote.

The top Democratic contenders include Matt Lieberman, the son of the former vice presidential candidate; former U.S. Attorney Ed Tarver and the Rev. Raphael Warnock, who pastors Atlanta’s Ebenezer Baptist Church.

The financial reports for federal candidates due Wednesday span a three-month period between Jan. 1 and the end of March, a stretch that coincided with a worsening coronavirus pandemic that drained bank accounts and sapped interest in political contests.
