One other accuser, Kelly Johnson, was allowed to testify during the trial as prosecutors sought to establish that Cosby had a pattern of assault.
But Cosby's spokesman Andrew Wyatt had some words of his own for Gloria Allred.
Prosecutors said they will retry the case.
"How do I describe many, but not all, general media?"
"Mr. Cosby does not intend to dignify these allegations with any comment".
Some of those who would otherwise have been following the testimony avidly and asking why Constand saw and kept calling Cosby after the assault - that was part of her job, she said - were instead following the testimony of fired former FBI Director James Comey and questioning why, if Comey didn't want to be left alone in a room with President Donald Trump, he kept talking to him on the phone. Constand said she took them with trepidation because she trusted him as the mentor and friend he was. "I look forward to her getting a verdict in the case". The incidents made her uncomfortable, but she continued to trust him because of who he was, the affidavit said. "The jurors, they used their power to speak".
The judge declared a mistrial after jurors deadlocked on the charges after six days. On Saturday, they came back and told O'Neill they were hopelessly deadlocked. By doing so, it "raised the question of whether some jurors are hoping to convince one or more others that any doubt they have expressed is unreasonable". "I feel bad for all of you, I really do". A new trial date has not yet been set.
Constand was one of dozens of women who accused Cosby of sexual assault over a decades-long time period, but hers has been the only one to result in a criminal trial.
Cosby told investigators in Pennsylvania that he gave Constand Benadryl and that the encounter was consensual.
Cosby lawyer Brian McMonagle says jurors might think they have to deliberate until "the cows come home".
Two US attorney generals to sue Trump
Trump of breaking many promises to keep his presidential responsibilities separate from his business interests, the report said. An artist in Washington , D.C. projected the "Pay Trump Bribes Here" message on the Trump International Hotel in May.
"We're talking about all the man's tomorrows", said McMonagle, urging acquittal of an icon in the twilight of life.
Cosby has been an icon in the black community following a successful career in comedy, including playing the lead role in his eponymous Cosby Show, which ran for almost a decade from 1984 until 1992.
But it was his reputation as a public moralist who urged young people to pull up their saggy trousers and start acting responsibly that prompted a federal judge to unseal portions of an explosive deposition he gave more than a decade ago as part of Constand's civil lawsuit against him.
Botwin, who said she attended four days of the trial, returned to the courthouse on Saturday with her toddler son.
Prosecutors argued Cosby drugged and sexually assaulted Constand.
In a statement to CNN, accuser P.J. Masten said she was "very disappointed that the judge did not allow other victims to testify". But I'm incredibly hopeful hearing the district attorney saying he would retry this case. According to the testimony, Cosby called himself a "sick man" but refused to identify the pills he gave to Constand. Constand alleges that the once-beloved TV dad drugged and sexually assaulted her in his home when she was an employee at his alma mater, Temple University.
"This isn't talking to a trustee".
Steele admitted he was "disappointed" but said his team would review their case and make tweaks.
"There are some things in this case that should be fuzzy. Why?" Before the trial, a probable cause affidavit laid out her version of events, which she says occurred between mid-January and mid-February of 2004.
