Lawyers for the rapper filed their appeal with Pennsylvania's Superior Court on Monday, the same day that the Philadelphia judge who jailed Mill denied to release him and called him a "danger to the community."
The 30-year-old rapper was sentenced to two to four years in prison last month for violating probation on a roughly decade-old gun and drug case.

The FBI says it does not confirm or deny investigations. The judge has had no comment.
