Los Angeles (CNN) -- The legal troubles threatening to send Chris Brown to prison for several years began with the singer's arrest five years ago in the brutal attack on then-girlfriend Rihanna. Brown has spent almost all of the past six months either in rehab or jail. He's been locked up since he was booted from a court-ordered substance abuse and anger management program on March 14. Brown has two pending criminal cases, both stemming from his alleged inability to control his anger. Brown's D.C. assault case Brown, 24, and his bodyguard, Christopher Hollosy, allegedly punched Parker Adams after a quick exchange of words on a sidewalk blocks from the White House last October. Brown was arrested on a felony assault charge, but it was reduced to a misdemeanor and he was released on bond the next day. The trial is set to begin Wednesday in D.C. Superior Court.
