(CNN) - Geraldine Ferraro has stepped down from her role as a member of Hillary Clinton's finance committee.
In a letter to Clinton obtained by CNN's Suzanne Malveaux - who spoke with the former vice presidential candidate shortly after she sent it to Clinton - Ferraro said she is stepping down so, "I can speak for myself and you can continue to speak for yourself about what is at stake in this campaign."
In a phone conversation with Malveaux, Ferraro said she was not asked to step down by Senator Clinton or her campaign.
Ferraro said thousands of people are part of the finance committee, saying it is not a staff position, but a voluntary one for those who raise money for the campaign. She also said she has raised $125,000 for Senator Clinton.
When asked if she had any regrets about what she said, Ferraro replied, "absolutely not."
"I am who I am and I will continue to speak up," she said. She added that she thought it was a shame that the Obama campaign was trying to block her First Amendment rights, and that she felt that was no way to conduct a campaign.
She said, "it's not me slicing and dicing," a reference to Obama's comments earlier in the day accusing Ferraro of dividing the party.
Ferraro said David Axelrod, Obama's campaign manager and an acquaintance, should have called her to ask her the intention of her remarks, which she says the Obama campaign used to hurt Clinton.
When asked how she felt about Hillary Clinton distancing herself from her remarks, Ferraro replied, "I am perfectly fine," and that there were no hard feelings. She said she understands what Clinton is going through, and understands that being part of a presidential campaign is "very hard."
Dear Hillary -
I am stepping down from your finance committee so I can speak for myself and you can continue to speak for yourself about what is at stake in this campaign.
The Obama campaign is attacking me to hurt you. I won't let that happen.
Thank you for everything you have done and continue to do to make this a better world for my children and grandchildren.
You have my deep admiration and respect.
