Nicki Clyne is featured in Episode 1 of HBO's "The Vow", Part Two, discussing her affiliation with NXIVM and her support for its founder, Keith Raniere.
Lauren Salzman, a top leader in Keith Raniere's cult, cooperated with the prosecution against Raniere and was the only member to testify against him.
"I am sorry to those of you that I brought into Nxivm," Mack wrote in a letter filed in court last week. "I am sorry I ever exposed you to the nefarious and emotionally abusive schemes of a twisted man."
Mack, 38, called the leader of the group a "twisted man" in a letter apologizing to those she harmed.
Tom Welling, Michael Rosenbaum and Allison Mack starred together in the show "Smallville" from 2001 to 2011.
A former NXIVM "slave" accused 'Smallville' actor Allison Mack of forcing members of Keith Raniere's secret sex cult to follow extreme diets for more than a year.
A woman took the stand and alleged "Smallville" actor Allison Mack invited her to an NXIVM group meeting where someone forcibly performed oral sex on her while she was blindfolded.
Lauren Salzman claimed Rosa Laura Junco was the only woman in Keith Raniere's all-female inner circle the NXIVM founder didn't have sex with.
Stone, who worked for Trump until a rancorous split in 2015, was once on the group's payroll.
Mack allegedly preyed on vulnerable women using a tactic described as "love bombing."
A whistleblower for the group told Newsweek that Mack was "deeply influenced" by charismatic leader Keith Raniere.
She allegedly recruited women for sex with the cult leader and helped brand them with his initials.
People have surmised that Mack is "co-conspirator No.1," in an abusive sex cult and also a slave to leader Keith Raniere.
