Federal prosecutors have asked an appeals court to uphold the conviction of former U.S. Rep. Corrine Brown on fraud and tax charges, pushing back against arguments that a juror was improperly replaced after he said the "Holy Spirit" told him Brown was not guilty.

Prosecutors last week filed a 69-page brief, as the U.S. Court of Appeals for the Eleventh Circuit prepares to hear arguments Feb. 22 about whether it should order a new trial.
