Richard Hatch Says Trump 'Slides Up' On Women

"Celebrity Apprentice" contestant Richard Hatch says he witnessed Donald Trump's lewd conduct with women repeatedly, and anyone claiming differently -- including his family -- is full of it.

Hatch, who famously won the first "Survivor" crown before working closely with Donald on 'Apprentice' ... says the boss made a habit of getting close to women as soon as they walked in the room. He adds ... Trump never took the hint either when they'd try to shake him.

Richard says he didn't witness the incident recently reported about Gary Busey allegedly groping a female staffer while Trump laughed. But he says he wouldn't be surprised if Donald and producers looked the other way, since they loved having his "crazy" on the show.

He also says Melania claiming others are "egging on" Trump's behavior ... is pure fantasy.
