Trump to Univision: You Can't Use My Golf Course

Donald Trump is firing back at Univision for ending its Miss Universe business relationship with him over his controversial Mexico comments.

Beside his statements Thursday that he is suing the network, Trump sent a letter to Univision president Randy Falco on Friday.

"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 also wrote to Falco that they should close down a gate "between our respective properties," saying if it wasn't done he would do it within the week, and told him it was too bad the Univision president didn't "have the courage" to call himself to announce the end of their deal.

In a "P.S." in the letter, Trump told the U.S.-based network president to "congratulate your Mexican government officials" for making "outstanding trade deals," which would end if he is elected president. He also said he would create a "meaningful border."
