(CNN) - Organizing for Action, the nonprofit advocacy group that originated from President Barack Obama's re-election campaign, raised $4.8 million in the first quarter from 109,582 donors.
The average donation was $44, according to an email the group sent to supporters Friday morning. This is the first report on its financial viability, as the group officially launched in January.
"To anyone who thought we couldn't do this, these numbers send a pretty clear message. It's never been done before, but supporters like you are doing it," Jon Carson, the group's executive director, stated in the email.
OFA has taken heat from some Republicans who argue the group is simply a conduit for wealthy donors to buy access to the president. But the White House has sharply denied meetings with the president could be purchased.
A 501(c)(4) group, OFA is not required to disclose all of its donors, but officials released a list of people who contributed more than $250 on Friday afternoon. The largest donation came from Philip Munger, a philanthropist, who gave $250,000.
The group maintains its purpose is to promote the president's second-term agenda, though some critics have also said it's an avenue for the president to get involved in 2014 mid-term elections.
Group officials have denied that was the case, and President Obama reiterated that point at a dinner with OFA supporters last month.
"I think here in Washington this idea has been viewed … both with suspicion, and people have been puzzled with what we're trying to do," he said. "Because the usual idea is, well, this must be a mechanism to win the next election in 2014, and what we've tried to explain to people is actually, I just want to govern. At least for a couple years."
Gun control, immigration reform and the president's fiscal proposals are among the legislative issues for which OFA has actively worked to build grassroots support this year.
