Donald Trump is doubling down on his opinions about Mexico.

The real estate mogul told Us Weekly that he won't back down on his comments, including the ones about Mexico sending "rapists" and drug dealers to the United States. "There's nothing to apologize for," he told the magazine. "Everything that I said is correct."

As a result of his comments, Univision announced on Thursday that it would not air the Miss USA pageant, of which Trump is a co-owner.

And as a result of that, Trump on Friday banned Univision employees from his Miami golf courses. (Univision is headquartered in Miami.)

Univision cancels Miss USA because of Trump's remarks about Mexicans

According to the Sacramento Bee, he wrote a letter to the Univision CEO informing him 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."

Univision's Miami office is adjacent to Trump National Doral, and Trump demanded in his letter that the network "immediately stop work and close the gate which is being constructed between our respective properties," within the next week, or else "we will close it."

Trump also added a "P.S" to the letter that read, "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."

Univision has not publicly responded to Friday's letter, though it did issue a memo to employees Thursday saying they should not stay at any of Trump's hotel properties while on business.
