Brown appeared Wednesday afternoon in a D.C. court. He and his bodyguard face a misdemeanor assault charge after an October altercation outside the W Hotel.
Speaking outside of court, Brown's lawyer, Danny Onorato said they had decided not to accept the plea because "Chris Brown's not guilty."
His lawyers say they expect a trial date to be set at another hearing, scheduled for Feb. 20.
At the time he was charged, 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.
