“Upon arriving at Weinstein’s suite, however, Weinstein quickly dropped his professional demeanor,” the suit states. “He instead overpowered Loman and raped her. Shocked and betrayed, Loman did not know what to do. Furthering Loman’s disorientation, Weinstein proceeded to treat the rape like a standard component of their business, as if the professional discussion he offered Loman had actually taken place.”

Loman also claims that Weinstein threatened her not to speak of the assault.
This is the second sex trafficking case filed against Weinstein.
Last week, a federal judge in New York ruled that British actress Kadian Noble can move forward with her sex trafficking lawsuit against the disgraced media mogul.
Noble accuses Weinstein of sexually assaulting her in a hotel bathroom in Cannes, France in 2014 after luring her with talk of a potential movie role.
Noble filed suit in November against Harvey Weinstein and his brother and then-business partner Bob Weinstein.
US District Court Judge Robert W. Sweet granted Bob Weinstein’s motion for dismissal but denied one from Harvey Weinstein.
The judge wrote it would be the first instance in which a plaintiff asked for the Trafficking Victims Protections Act to be applied to conduct like that alleged in the lawsuit.
Weinstein’s lawyer said the act should not be applied.
“A typical sex trafficking case is someone who lures underage girls on the promise of a green card and locking them up in a basement and forcing them to have sex for money,” Kupferstein said in a statement at the time.
Weinstein, who also is facing criminal charges in New York, has denied all allegations of “non-consensual sexual activity.”
Weinstein has pleaded not guilty to six felony sex crimes — two counts of predatory sexual assault, two counts of rape, one first-degree criminal sex act charge and one criminal sex act.

The charges stem from allegations from three women, according to court documents. Weinstein remains free after posting $1 million cash bail.
The charges against Weinstein came nine months after The New Yorker and The New York Times published accounts from several women accusing him of various forms of sexual misconduct.
In a recent interview with CNN, Ben Brafman, Weinstein’s New York criminal attorney, said it would be “difficult but not impossible” to seat an impartial jury should Weinstein’s case move forward to trial.
“I hope to find 12 people in Manhattan who may have heard a lot of the allegations against Mr. Weinstein but will give the court their sworn assurances that they will decide this case based on the evidence that comes into the courtroom and not on what they made have read, or what they may have heard,” Brafman said. “I think part of what we’re trying to suggest in these motions to dismiss is that contrary to what people may have read and may have heard, there is another side here.”
