(CNN) - Tea Party-backed Rep. Michele Bachmann of Minnesota raised $5.4 million in the third quarter, her campaign announced Wednesday.
Federal Election Commission financial disclosure reports aren't due until October 15, but Bachmann press secretary Sergio Gor confirmed the number to CNN and said she now has $3.4 million cash-on-hand.
"I am so grateful to the more than 80,000 people who have contributed to my campaign this quarter," Bachmann said in a statement. "Their support is truly overwhelming and I am blessed."
Bachmann's coffers may have benefitted from her growing national presence. The conservative star founded the Congressional Tea Party caucus earlier this year, and has stumped regularly during the campaign season in support of Republican candidates.
Former Alaska Gov. Sarah Palin has also been a vocal supporter of Bachmann.
The announcement comes on the heels of another Tea Party favorite's surprising fundraising feat. Sharron Angle, the Republican Senate nominee in Nevada raised $14 million in the last quarter, her campaign said.
Bachmann will face Democratic challenger Tarryl Clark in November for control of Minnesota's 6th Congressional district.
