>> Bill Cosby's primary accuser taking the stand Tuesday. Former Temple University employee Andrea Constand testifying with harrowing details, that the comedian drugged and sexually assaulted her in 2004. Constand described Cosby as a mentor, someone she trusted. One night he allegedly gave her what he said were herbal pills, then she told the court she felt frozen.
He then groped and molested her as she couldn't move, adding quote, I wanted it stopped. Reuters legal correspondent Joseph Axe was at the courthouse, Tuesday.>> This was a big moment in the Bill Cosby scandal. This was the first time they'd been face to face in a long time, since all this broke.
And while she was describing to jurors what she said happen at his home, on his couch. He was shaking his head, he was putting his hand over his forehead, he was whispering to his attorneys. But he was clearly registering that he disagreed with her testimony. Constand, mostly kept it together, she didn't cry much that I saw.
Her voice quavered at times, but she was a pretty strong witness in terms of kind of her demeanor. She told the story, she didn't get too emotional. And even during cross-examination when the defense was going after her fairly hard, she didn't crack at all. And this was the dramatic moment that everyone had been looking for when this trial began.
She's clearly the hinge on which the outcome of the trial is gonna turn. And so it was a pretty dramatic moment when she took the stand. She walked into the courtroom, there was a lot of murmuring. And then when she first began to talk about her relationship with Cosby, people in the audience were riveted.
>> Dozens of women have accused Cosby of sexually assaulting them under similar circumstances in a series of attacks dating back to the 1960s. Cosby, who his lawyers say is legally blind, is not expected to testify, though he has denied allegations against him.
