Greenberg has said that the documentary proved nothing.
"The allegations aren't true because he never knowingly had sex with an underage woman, he never forced anyone to do anything, he never held anyone captive, he never abused anyone", Mr Greenberg told the Associated Press.More news: Trump says record-long govt shutdown could be resolved 'in 15 minutes'
More recently, many said he runs a hidden "sex cult" of women manipulated and abused to stay away from the outside world and under his control.
R. Kelly's daughter Joann Kelly, aka Buku Abi, with whom he is estranged, called him a "monster" on Instagram, writing: "I am well aware of who and what he is". Lifetime did not immediately respond to a request for comment.

While initially Greenberg said he "didn't watch one minute" of the series because he doesn't "watch that kind of trash", the lawyer eventually acquiesced that he's "seen snippets of it". He asserted that in the past women have "come on to" Kelly in the hopes that he could help them in their own performing careers, then became "disgruntled" when their own careers stalled and issued false allegations.
After the documentary aired, singer Lady Gaga vowed to remove a duet she recorded with Kelly from streaming services and never collaborate with him again.
The Lifetime series featured interviews with several women making on-camera allegations of sexual, mental and physical abuse by Kelly, as well as interviews with some of his former managers and producers.More news: Samsung Galaxy S10's release date announced
"There's women saying things, which is of course their prerogative, but there is no evidence that any of it happened", Greenberg said of the documentary. On Jan. 7, the day after the series ended, Kelly's songs were played on radio 198,000 times.
