Donald Trump is taking aim at NBC after they cut ties with him over his controversial remarks on immigration.

The network announced Monday that they will no longer air the Miss USA and Miss Universe pageants.  Trump owns part of the Miss Universe Organization, which puts on the shows.

In a statement, Trump called the network weak and foolish for not understanding what he believes is a serious illegal immigration problem.  Furthermore, he threatened to take legal action for backing out a signed contract.

Trump also blasted NBC for standing behind a quote, "lying Brian Williams," but not backing him. (Metro Networks Inc.)
