(CNN) - President Obama's attacks on Karl Rove and conservative outside organizations could be firing up someone's base: Rove's.
An official with American Crossroads, the conservative third party organization Rove advises, and its affiliate, Crossroads GPS, claimed they received $30,000 in unsolicited online donations this Sunday alone. Crossroads GPS is not legally required to disclose its donors. The official says the contributions were almost all small dollar gifts over the internet accompanied by notes encouraging the group to push back on the president.
Appearing on Fox News Sunday, Karl Rove refuted attacks from the president and the Democratic National Committee that his group and the chamber of commerce were bending campaign finance laws. That seemed to fire up at least one contributor. A woman who identified herself as a housewife sent in $100 online and wrote, "Great pushback just now on Fox News Sunday, Mr. Rove! I'm sick of the bullying by the Dems- it has gone on too long without fighting back!"
One American Crossroads official expressed some amazement at the uptick in donations – explaining that its unusual because the group hasn't made an online fundraising pitch. The official says "its all incoming".
Steven Law, American Crossroads' President and CEO, says he believes the president's campaign rhetoric is firing up conservatives because "people see it as an abuse of power, which is what they already dislike about the current regime in Washington."
His group went out of its way to tell CNN the $30,000 that came in Sunday was from "all 100% American donors".
That's a reference to allegations that the US Chamber of Commerce has allowed contributions from foreign sources to fund its domestic political efforts – a violation of election law if proven to be true.
Obama has made this an issue on the campaign trail. At a Philadelphia rally Sunday, the president said, "The American people deserve to know who is trying to sway their elections" adding "you don't know...it could even be foreign-owned corporations."
American Crossroads did not supply CNN with a total number of contributions over the weekend.
