PHILADELPHIA (AP) — Bill Cosby is switching law firms to oversee civil lawsuits around the country that involve accusations he drugged and molested women.

A Cosby spokesman confirms Monday that litigation chairwoman Angela Agrusa of Liner LLP is replacing lawyers with Quinn Emanuel Urquhart & Sullivan. Both firms are based in Los Angeles.

Agrusa, in a statement, says she won't try the defamation and sex-assault cases in the press.

The Liner firm represents singer Blake Shelton in a defamation case against a celebrity magazine. The firm also defended the doctor charged with overprescribing painkillers to the late model Anna Nicole Smith.

Spokesman Andrew Wyatt says Quinn Emanuel may stay involved in the criminal sex-assault case in suburban Philadelphia. The firm's Christopher Tayback last week argued unsuccessfully for the charges to be dismissed.
