The Donald is at it again. The reality TV star turned Republican presidential candidate has called for a boycott of Univision Communications Inc after the broadcaster severed ties with him following his anti-immigrant comments in his candidacy announcement speech.

The 69-year-old tweeted to his 3 million followers on 26 June, "Anyone who wants strong borders and good trade deals for the US should boycott @Univision." Trump also released his letter to the company's CEO and president Randy Falco banning Univision employees from using his Miami hotel.

"Please be advised that under no circumstances is any officer or representative of Univision allowed to use Trump National Doral, Miami—its golf course or any of its facilities," Trump wrote.

The Republican candidate added a post script that was nearly as long as his letter.

"PS Please congratulate your Mexican Government officials for having made such outstanding trade deals with the United States. However, inform them that should I become President, those days are over. We are bringing jobs back to the US. Also, a meaningful border will be immediately created, not the laughingstock that currently exists," he added.

According to the Daily Mail, Trump also posted on Instagram a photo of a handwritten letter sent to him by Univision news anchor Jorge Ramos, which included the anchor's personal mobil number. That post has since been deleted.

Trump's calls to boycott the network comes a day after the real estate mogul told TMZ that he plans to sue Univision for "hundreds of millions of dollars." The broadcaster announced that it was severing ties with Trump and would not be airing the Miss USA pageant on 12 July following his comments about Mexican immigrants.

He has faced backlash from many involved in the Miss Universe pageant, which he partially owns. According to the Daily Mail, former Miss Universe and president of Nuestra Belleza Mexico Lupita Jones is threatening to pull Mexico's representative from the pageant after his comments.

Roselyn Sanchez and Cristian De La Fuente, who were scheduled to co-host the Spanish-language version of Miss USA, both dropped out of the hosting duties following Trump's comments.

Sanchez issued a statement in Spanish on Instagram, saying, "As a Latina and proud of my roots, culture and everything we have contributed to this nation, I have decided to cancel my participation as co-host of Miss USA. I don't tolerate the disrespectful and hurtful words that came out of Mr. Trump's mouth."

Chilean actor de la Fuente, who co-stars with Sanchez on Devious Maids, posted his own response in a Facebook video. "It is unacceptable to launch a presidential candidacy created on a rhetoric of hatred and discrimination in calling Mexicans drug dealers and rapists. It is a shame that such an important institution as Miss USA is in the hands of a clown."

Trump did not appear to take de la Fuente's comments too seriously, telling TMZ, "We never even signed the guy. After the Miss USA people saw him they were unimpressed."

According to PEOPLE, NBC, which airs Miss USA in English, distanced itself from Trump's remarks. "Donald Trump's opinions do not represent those of NBC, and we do not agree with his positions on a number of issues, including his recent comments on immigration."

In an attempt to clarify his comments, Trump said they referenced all immigrant groups, not just Mexicans. "I didn't say it about Mexico," he allegedly said. "I said people from all over."
