(CNN) - The Republican National Committee raised $10.3 million in September, dramatically up from their August total but far less than the $16 million the Democratic National Committee brought in last month.
An RNC spokesman confirmed the numbers to CNN Friday. Earlier Friday a Republican source with knowledge of the numbers put the total at $9.7 million, which was first reported by the Hill.
The DNC unveiled their fundraising figures Monday. Neither party committee is required to report its fundraising totals until later this month. But the Democrats were eager to promote their big cash haul, as try to hold onto their majorities in Congress in the midterm elections amid a tough political climate that appears to favor Republicans.
The RNC's $10.3 million is about one million less that what had been projected for September. The RNC raised $7.7 million in August. The DNC brought in $11 million in August.
The September figures could be troubling for RNC Chairman Michael Steele, who has faced criticism for his handling of the committee's finances during his nearly 20 months steering the RNC.
But the Republican Party's Senate and House committees have been staying more competitive with their Democratic counterparts and outside groups, such as American Crossroads, have been raising millions and spending millions on political advertising and get out the voter efforts.
