Bill Cosby's lawyers are trying to undermine his chief accuser's credibility by questioning why she promoted an alleged pyramid scheme. "I didn't know what was happening", she said.
Prosecutors also sought to deflate another prong in the defence strategy, asking Constand about her former Temple colleague Marguerite Jackson.
Cosby is charged with drugging and assaulting another woman at his home in 2004. The defense attorneys are once again expected to argue that the encounter was consensual.
The Associated Press doesn't typically identify people who say they're victims of sexual assault unless they grant permission, which Constand and Thomas have done.
It's the same disturbing story that so many accusers have shared.
In opening arguments on Tuesday, Mesereau said Cosby was lonely and vulnerable at the time, having never recovered from the 1997 murder of his son, Ennis, by a street punk in Los Angeles.
Lise-Lotte Lublin, another accuser who testified Thursday, told jurors she lost consciousness and doesn't remember anything else about her alleged encounter with Cosby in 1989.
The trial took a far more combative turn Tuesday than the first go-round.
Bill Cosby arrives to Montgomery County Courthouse for the fifth day of his retrial for sexual assault charges, April 13, 2018, in Norristown, Penn.
Constand testified she chose to report the assault to police in January 2005, about a year later, jarred to action by a nightmare and an increasing awareness of consent issues from her ongoing massage therapy training.
The defense calls Constand a "con artist" who made up her allegation in order to file a civil suit against Cosby. But they failed to make clear why jurors should care that the comedian paid a $3.4 million settlement to accuser Andrea Constand. According to the defense lawyer, Constand replied: "No, but I can say I was".
Judge Steven T. O'Neill has ruled that Jackson can testify, but said that ruling is subject to change, pending how other testimony goes at trial.
Constand was on the stand for an hour and four minutes, before the prosecution steered her toward the night in question, when she went to Cosby's house to discuss her impending resignation.
More than 50 women have come forward to accuse Cosby, all before the explosion of #MeToo. But when she developed double vision and started slurring her words, Cosby lay her down on a sofa.
During a spirited cross-examination, Cosby's defense attorney, Tom Mesereau, asked why a passage in Dickinson's 2002 book about the Lake Tahoe visit does not say she and Cosby had sex.
Bill Cosby's chief accuser has told a jury that he drugged her with three blue pills and then sexually assaulted her at his suburban Philadelphia home in 2004.
Constand is one of dozens of women who have accused the iconic comedian of drugging and then assaulting them, but she is the only one whose allegation became the focus of a criminal charge. Cosby's lawyers plans to call Jackson as a witness and say she will testify that Constand mused about framing a celebrity before she lodged sexual abuse allegations against Cosby in 2005. Cosby gave her three blue pills that he said would relax her. "I looked at Mr Cosby, and I said: 'I see two of you'".
"Recounting that phone conversation, Constand said, "'You put your fingers inside my vagina, and you touched my breasts, and you took my hand and put it on your penis, '" she testified. The first trial ended in a mistrial last June after the jury was deadlocked and unable to reach a verdict. Cosby paid her $3.4 million in a 2006 civil settlement.
Cosby lawyer Jaya Gupta told a judge Wednesday that Chelan Lasha's 2007 guilty plea for making a false report to Arizona law enforcement "bears on her veracity".
How Ms Constand's testimony will play with the seven men and five women of the jury will hold the key to Cosby's fate.
The 45-year-old Constand says Cosby drugged and molested her at his suburban Philadelphia mansion in January 2004.
Constand offered brief details of seven social encounters she had with Cosby before the alleged assault, including one in which she said he put his hand on her thigh and another when she said he tried to "unbutton my button on my trousers". This time, the prosecution was allowed to call five additional Cosby accusers who claim they were sexually assaulted by Cosby in an attempt to prove a pattern of criminal conduct by the famous defendant.
Andrea Constand's testimony on Friday makes for a climactic courtroom showdown after five other women told jurors that the man once revered as "America's Dad" is a serial rapist who harmed them too.
Leading up to Constand's retelling of the alleged assault, the former Temple University employee on Friday traced her relationship with Cosby, whom she said she met while handling operations for the school's women's basketball team. Constand said she also spoke with Cosby to arrange tickets for her family to attend one of his shows.
