Doral Police Chief Hernan Organvidez told reporters officers confronted the man about 1:30 a.m. Friday and exchanged fire. He said the man was "neutralized" and taken into custody.
Miami-Dade Police Director Juan Perez said the man was shouting about Trump, and draped an American flag over the counter. He said the man was "actively shooting."
Perez said a Doral officer received an unspecified injury.
The golf resort previously known as the Doral Resort & Spa was purchased by the Trump Organization in 2012. Its signature course is the Blue Monster at Doral.
