The R&B singer was arrested in October after a man said the singer hit him outside the W Hotel. Brown and his bodyguard each face a misdemeanor assault charge.
Brown is expected in court Wednesday afternoon.
At the time of the alleged assault, the Grammy winner was on probation in California for a 2009 attack on singer Rihanna, his then-girlfriend. As a result of the charge in Washington, a judge revoked Brown's probation in California, but the ruling didn't alter a requirement that Brown complete rehab and community service including roadside cleanup and graffiti removal.
