Cindy McCain, the widow of late Sen. John McCain, blasted authorities who were "afraid" to arrest convicted sex trafficker Jeffrey Epstein even though everyone "knew" what he was doing.

"Epstein was hiding in plain sight," said Cindy McCain. "We all knew about him. We all knew what he was doing, but we had no one that was — no legal aspect that would go after him. They were afraid of him. For whatever reason, they were afraid of him."

McCain's comments came after she was questioned by an attendee during her appearance at the State of the World 2020 conference in Florida.

McCain said a girl from her daughter's high school was one of Epstein's victims and that she hopes Epstein "is in hell."

Epstein's massive wealth and his connections to powerful politicians and celebrities allowed him to continue trafficking young women and girls long after many had exposed his devious interests.

Dr. Barbara Sampson, the New York City medical examiner, said Epstein died by suicide at a Manhattan federal detention facility last August. His death and the circumstances surrounding it have created controversy after the former medical examiner of New York, Dr. Michael Baden, told 60 Minutes that he believes Epstein was murdered.

Cameras from outside Epstein's jail cell failed to record footage on the night of his death, and guards who were supposed to monitor him every 30 minutes fell asleep when the former financier died.
