New York (TheStreet) -- Has Donald Trump had his "oops" moment?
After years of acting the part of the rich, loud-mouth businessman, Trump 's harsh characterization of Mexicans and Mexican-Americans when announcing his candidacy for president could snuff out his fledgling political career even before it gets started.
At least former Texas Governor Rick Perry made it to a GOP presidential debate before he imploded. Perry forgot a key detail of his platform and helplessly muttered the now-famous "Oops."
Trump's career has mixed together skyscraper developments with casinos -- some bankrupt -- a bevy of platinum blonde women -- some of them related -- and a variety of attempts -- some serious -- to launch a political career.
But his sweeping characterization of Mexican immigrants as little more than drug-runners, thieves and rapists was apparently enough to convince Comcast's ( CMCSA) NBC on Monday to end its relationship with the 69-year-old Queens, New York-born real estate developer.
"At NBC, respect and dignity for all people are cornerstones of our values," read the e-mailed press release. "Due to the recent derogatory statements by Donald Trump regarding immigrants, NBCUniversal is ending its business relationship with Mr. Trump."
NBC said it wouldn't air the Miss USA and Miss Universe Pageants, and that Trump wouldn't participate in the networks long-running show The Apprentice. The Miss USA pageant was scheduled to be aired on NBC on July 12.
A multi-billionaire, Trump angered many across the political spectrum with his comments about immigration and crime during a June 16 speech announcing his candidacy for the Republican presidential nomination.
"When Mexico sends its people, they're not sending their best," Trump said before a crowd of supporters. "They're not sending you. They're not sending you. They're sending people that have lots of problems, and they're bringing those problems with us. They're bringing drugs. They're bringing crime. They're rapists."
