She was found not guilty of two mail fraud counts and two wire fraud counts.
Federal prosecutors at the time said Brown used the charity she founded, One Door for Education Foundation Inc., as a "personal slush fund".
Evidence showed that the One Door for Education - Amy Anderson Scholarship Fund raised more than $800,000 in donations but gave away only two scholarships totaling $1,200 to students, the Justice Department said in a statement.
Simmons said Brown ordered how all of the One Door money was spent and no one in her office ever dared to tell her "no".
The group was indicted in 2016, and Brown stepped down from her congressional leadership post - though not her congressional seat - after the charges were announced. If convicted on all charges, she could be sentenced to more than 350 years in prison. She also says she didn't know her chief of staff was putting thousands into her account and taking well over $100,000 for himself.
A juror accused of making a questionable comment has been excused from deliberations in former U.S. Rep. Corrine Brown's fraud trial. She didn't speak after the verdict was rendered, though her attorney James Smith told reporters, "I still have a lot of work to do on this case", referring to the sentencing phase of the trial that's still to come and the motion he plans to file for a new trial.
Brown argued that she was minimally involved in preparing those returns and that, at least one year, she did not sign it herself.
Brown, who maintains her innocence, refused to answer questions while leaving court.
Smith pointed to the case of former Virginia Gov.
In a statement released after the verdict was announced, Acting U.S. Attorney W. Stephen Muldrow said "Former Congresswoman Brown chose greed and personal gain over the sacred trust given to her by the community that she served for many years".
Brown was elected to Congress in 1992 as one of the first three black members of Florida's congressional delegation since the Reconstruction period following the Civil War.
"It was a mistake on my part and I needed to get on top of my taxes", Brown said.
It's just one of the dozens of projects she was involved with, including replacing the aging Veterans Affairs clinic, with a new state-of-the-art facility.
"She was calling on her own behalf, but thought that other jurors were concerned as well", said Judge Corrigan. Our lives are films, and you have to look at each and every frame.
