Update: The campaign now says it’ll release 24-hour fundraising numbers at 3:05 pm today on Daily Kos and the Huffington Post. His Act Blue donations as of 2 pm Saturday are approaching $180,000, raised since yesterday.

Democrat El Tinklenberg’s campaign has received an “overwhelming” amount of contributions since his Republican opponent, Rep. Michele Bachmann, told MSNBC’s Chris Matthews that she believed the media should investigate whether members of Congress are “anti-American.” But, as the money’s coming in so quickly, the campaign can’t yet give firm numbers.

Tinklenberg’s communications director, Kate Monson, told MnIndy that online support has been strong, and that donations coming through Act Blue — $128,000 currently, coming from more than 3,000 supporters — has been one of many ways the campaign has been accepting funds. She wouldn’t give an estimate for direct donations to Tinklenberg08.com. “We’ve had an overwhelming amount of online support,” she says. “We’re still counting so it’s impossilbe to give an accurate estimate.” She says the campaign will make an announcement of the figure Monday morning.

Asked why Tinklenberg’s website doesn’t mention Bachmann’s words, she promised, “There will be a response at the right moment.”

Finally, she dispelled rumors that the Tinklenberg website was having troubles due to the increased volume of traffic. “We believe we have the capacity to continue” at this level of traffic, she added.

An online petition to censure Bachmann, which is not affiliated with the Tinklenberg campaign, now includes more than 18,000 signatures.
