Pugh released a statement that was read to the media by her attorney.
"Dear citizens of Baltimore, I would like to thank you for allowing me to serve as the 50th mayor. It has been an honor and a privilege," the statement read.
"Today I am submitting my resignation to the Baltimore City Council," she continued. "I am sorry for the harm that I have caused to the image of the city of Baltimore, and to the credibility of the office of the mayor."
She earned hundreds of dollars over sales of her children's books meant to encourage healthy behavior, but some of those appeared to be by entities that she had political power to influence.
One reported indicated that hundreds of boxes of the unused books were abandoned in a storage facility.
Here's the latest in the Pugh resignation:
