The retrial of the American actor and comedian, Bill Cosby, is due to begin in Pennsylvania on Monday.
Mr Cosby, 80, denies drugging and sexually assaulting former basketball player Andrea Constand 14 years ago.
The first trial, in June 2017, ended when the jury failed to reach a verdict, reports BBC.
The actor, who starred in the 1980s TV series The Cosby Show, has faced allegations from dozens of other women but has denied them all.
Mr Cosby enjoyed a family-friendly reputation for years before numerous sexual assault allegations came to light in 2015.
The retrial takes place in the light of the #MeToo movement, which has raised awareness of alleged sexual misconduct by a number of powerful media figures.
Protesters, waving placards reading "justice for survivors", gathered outside the courtroom ahead of the retrial.
A topless protester was dragged away by police.
Mr Cosby has been charged with aggravated indecent assault, a second degree felony, by the Pennsylvania prosecutor. The charge could carry a prison sentence of up to 10 years.
His lawyers say he and Ms Constand shared a romantic relationship after they met at Mr Cosby's old university.
Ms Constand, who is from Canada, had played basketball professionally in Italy and for Canada's national women's team.
When the attack took place, Ms Constand was working as director of operations for the women's basketball team at Temple University, Philadelphia, where Mr Cosby is an alumni.1
