One volunteer attending the morning meeting believes the criticism and questions are unfounded.
"I think the people who say, 'Oh its got the potential for this and that,' I say: 'Trust us,' said Carlotta Joyner, a Maryland volunteer who helped both Obama campaigns and now works with OFA.
Noting the group's promise to disclose donors who gave over $250, Joyner continued: "I would say, take a look at the website. Do you know who paid $500,000? I think that's a big difference from people who put that kind of money into other [similar] organizations and you don't know who they are."
"I have not heard or seen any promise that if you give this amount of money, this is what you'll be able to do. You'll be able to talk to the president for x-number of minutes."
The dinner with OFA comes as the president negotiates with congressional Republicans on a grand bargain to fix the country's fiscal problems. Administration officials, speaking on condition of anonymity, told CNN they don't see the president's appearance at OFA as an opportunity to push Republicans on a grand bargain. But they hinted that the president will continue to travel around the country to make his case.
