Trump dumped: Mexican billionaire Carlos Slim drops joint TV project as mogul sues for $500m

Donald Trump cannot catch a break. Mexican billionaire Carlos Slim has become the latest to cut ties with the real estate mogul after his anti-immigrant remarks during his presidential campaign announcement speech.

"We can confirm that we were working on a television project with Trump that has been dropped," a spokesman for Slim's Ora TV told CNNMoney. OraTV is a production company that was co-founded by Slim and TV personality Larry King and funded by America Movil, Reuters reported.

Slim's spokesman and son-in-law Arturo Elias told Reuters: "His statement was totally out of line...working with someone so closed-minded was not going to work."

Ora TV is the third company to sever ties with the controversial Republican candidate. On 29 June, NBC announce it would not be airing Miss USA and Miss Universe pageants due to Trump's comments.

"At NBC, respect and dignity for all people are cornerstones of our values," the statement said. "Due to the recent derogatory statements by Donald Trump regarding immigrants, NBCUniversal is ending its business relationship with Mr. Trump."

Spanish-language network Univision was the first to part ways with the reality TV star on 25 June. Univision and NBC both announced they would not be airing the Miss USA pageant on 12 July or working with Trump on other projects.

Trump, who announced his presidential bid on 16 June in a speech riddled with controversial comments, has threatened to sue both NBC and Univision. On 30 June, Trump announced he had filed a $500m lawsuit against Univision, Business Insider reported.

In a statement announcing the lawsuit, Trump said: "As a consequence of their inappropriate actions, Univision and NBC have abandoned fifty one wonderful young women who have come from all over the United States to pursue their dream of being crowned Miss USA."

Trump also said Univision was trying to "suppress his freedom of speech". "While Univision claims its decision came solely in response to comments by Mr. Trump during a 16 June 2015 campaign speech announcing his candidacy for President of the United States," the statement said, "the decision was, in reality, a politically motivated attempt to suppress Mr. Trump's freedom of speech under the First Amendment as he begins to campaign for the nation's presidency."

Univision has not commented on the lawsuit.

A petition on MoveOn.org is also urging retail company Macy's to end its relationship with Trump and drop him as one of their spokespersons. The petition, which has over 715,000 signatures, lists various reasons for the company to drop Trump, from his candidacy announcement to his racist comments.

The candidate has used social media, such as Twitter and Instagram, to hit back at his critics and continue to lash out against the Mexican government.
