Donald Trump -- NBC is 'Weak' ... Threatens Lawsuit

Donald Trump says NBC is "weak" for firing him, and he's threatening them in court.

Trump says NBC is a prime example of why our country is in serious trouble ... because it's so worried about offending, it is blinding itself to the immigration problem.

Trump says, "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."

Short story -- The Donald is threatening NBC the way he's threatened Univision, for allegedly breaching an iron-clad contract by pulling the plug on him.
