Cuomo’s cheating on Sandra Lee was "an open secret," sources say

Sources told The Post how Cuomo threw boozy parties at the pool house in the governor’s mansion and “movie nights” attended by female staffers, all without Lee, who often traveled to the West Coast to care for her family.

While it is possible that such events were innocent — if awkward — morale-building exercises for the many staffers (male and female) in attendance, these details form part of the pattern that emerged after former staffers spoke out about inappropriate behavior where lines between Cuomo’s personal and professional lives became blurred.

Five former Cuomo staffers told The Post they are convinced he became involved, or pursued intimate relationships, with a small number of staffers while living with Lee.

“It was an open secret,” said one ex-aide. “Andrew was sleeping with at least one other woman who wasn’t Sandra” before they officially ended their relationship.
