The longtime California democrat is accused of seeking federal assistance for a bank with ties to her husband.
Waters spoke with KCRW's Warren Olney on Thursday about her case. She said she has not violated any congressional ethics rules.
When Olney asked Waters if she had anything to do with $12 million that OneUnited Bank received, she replied: "No, as a matter of fact you have to qualify for tarp through the [Federal Deposit Insurance Corp.]. The qualifications are spelled out in the law that they organized in order to consider banks. They didn't take calls from elected officials, from members of Congress or anybody and they've said so."
The committee investigating Waters said she has been charged but it has not offered specific details.
Waters has asked that panel to release all public documents related to her case and to set a hearing date.
