Former U.S. Rep. Corrine Brown was sentenced Monday to five years in federal prison for fraud and tax crimes that included raising about $800,000 for a sham charity.

Brown’s longtime chief of staff, Ronnie Simmons, was sentenced to 48 months in prison, and the charity’s founder, One Door for Education President Carla Wiley, was sentenced to 21 months.

U.S. District Judge Timothy Corrigan said he believed Brown used her position in Congress to achieve an “admirable record of service.” However, he also said she abused the trust of that office in order carry out a criminal conspiracy.

“This is a sad day for everyone,” Corrigan told Brown shortly after sentencing her. “I was impressed with all the outpouring of support for you, and I think it’s a tribute to all the work you’ve done over the years. That’s what makes this all the more tragic.”
