From the story here:
After NBCUniversal severed its relationships with Donald Trump on Monday, the billionaire businessman and presidential candidate responded by invoking suspended NBC anchorman Brian Williams and threatening to meet NBC in court. ...
"If NBC is so weak and so foolish to not understand the serious illegal immigration problem in the United States, coupled with the horrendous and unfair trade deals we are making with Mexico, then their contract violating closure of Miss Universe/Miss USA will be determined in court. Furthermore, they will stand behind lying Brian Williams, but won't stand behind people that tell it like it is, as unpleasant as that may be."
