Michael Jackson Was a Sexually Abusive Monster & Everyone Knows It - Wade Robson

Wade Robson, through his attorney, is elaborating on his recent sexual abuse claim against the late Michael Jackson, who he calls an abusive monster. One who threatened and brainwashed him, no less.

Henry Gradstein tells TMZ that Wade Robson, 30, was molested by the King of Pop at Neverland Ranch and his other homes between ages 7 and 14.

As for why Wade didn't come forward until now - and even testified under oath that Michael was innocent, as Jackson's lawyers pointed out immediately?

"Last year, on a career trajectory that was off the charts, he collapsed under the stress and sexual trauma of what had happened to him for seven years as a child."

The attorney adds that Robson carried the weight of long-repressed, emotional "brain washing by a sexual predator until the burden of it all crushed him."

Gradstein says MJ would tell Wade, "If anyone ever finds out about what we did we will go to jail for the rest of our lives ... our lives will be ruined forever.”  

From Wade's standpoint, it worked, as he went so far as to lie on the stand during Michael Jackson's 2005 molestation trial to protect his abuser.

Wade was steadfast for years that MJ did NOT molest him, something that is not lost on his attorney, who says it is not Robson's fault, but rather:

"Such intimidation of a child by a sexual predator is tragically characteristic and effective, keeping them quiet about the abuse - often for a lifetime."

"Michael Jackson was a monster and in their hearts every normal person knows it."

Robson filed a creditor's claim against Michael's estate earlier this week, alleging that the music icon molested him as a child and asking for damages.
