The feud between Donald Trump and Univision continues. The Presidential candidate sent a letter to Univision's CEO Randy Falco, saying that the company's employees were barred from enjoying his Miami golf resort.

The letter explained that "under no circumstances" were the officers and reps of Univision allowed to use his Trump National Doral Miami courses, which included the golf course and "any of its facilities."

"Please be advised that under no circumstances is any officer or representative of Univision allowed to use Trump National Doral, Miami - its golf courses or any of its facilities," Trump wrote in his letter to Falco, according to ABC News.

Trump also took a jab at Falco's management style, writing, "It's too bad you didn't have the courage to call me yourself instead of delegating the task to Beau."

He concluded the letter, writing, "P.S. 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 U.S. Also, a meaningful border will be immediately created, not the laughingstock that currently exists,"

Trump's letter was sent a day after Trump threatened to sue the Spanish-language network for dropping coverage of his annual Miss USA pageant. Univision, which is the biggest Spanish-language television channel, parted with Trump after he made negative remarks about Mexican immigrants.

"When Mexico sends its people, they're not sending they are best ... They're sending people that have lots of problems, and they're bringing those problems with us," he said during his announcement for presidency. "They're bringing drugs. They're bringing crime. They're rapists."

Univision Communications Inc. released a statement about the decision to drop the beauty contest, which read, "At Univision, we see firsthand the work ethic, love for family, strong religious values and the important role Mexican immigrants and Mexican-Americans have had and will continue to have in building the future of our country."

As of Monday, NBC Network has announced that they will no longer have a business relationship with Trump.
