Brown joined Jackson at Saturday's meeting of the Rainbow PUSH Coalition, which he heads.
He filed a suit accusing her of not releasing funds for a peer jury program.
The program is designed to put youths with minor criminal offenses into mediation instead of the juvenile justice system.
Brown was quoted as calling the program unconstitutional, but she denies saying that.
Brown insists she supports the program and is distributing money to make it work.
"We're properly collecting them, and we're allocating them to particular municipalities," said Brown. "We want to make sure that they're getting to the right sources."
"Resources should be set aside appropriately for juveniles as diversion from jail," said Jackson. "She's working on that. We're working on it together."
Jackson said his suit against Brown is being modified and was never meant as a personal attack.
