That's not Marriott's contention. From the article in the OP:
Marriott contends in its motion that, the day after the incident, the NFL “sent its investigator to the Hotel and asked if the Victim was willing to speak with her.” The unnamed Marriott employee agreed to the interview, repeating her version of the interaction with Irvin.
“The NFL investigator then asked to review the video and the Hotel allowed her to do so,” Marriott’s lawyers wrote. “Following her review of the video, the NFL investigator escalated the matter and additional NFL personnel quickly arrived at the Hotel.”
Marriott’s lawyers contend that, from this point forward, the NFL took over the situation, culminating in Irvin being removed from the hotel.
