The district attorney's office said in court on Monday they will oppose Brown getting out of prison.
Brown's defense attorney says he will file a motion to remove the district attorney from the case, saying Brooke Jenkins is trying to prove she is independent from the mayor who appointed her.
The next court hearing is in December.
