Geragos has since issued a statement to The AP over prosecutors' claims that the 'Don't Judge Me' has not fulfilled his probation terms.
The attorney branded the motion as "shameful and a disgrace", adding: "In essence, it calls everyone a liar in the Richmond Police Department and the Virginia Probation Department."

Geragos also revealed that he plans to seek sanctions against the D.A.'s office for a what he called a "frivolous, scurrilous and frankly defamatory motion."
The Los Angeles County DA's office has declined to comment on Geragos's claims.
Brown is due to appear before a court in Los Angeles tomorrow (February 6).
