SACRAMENTO — Presumptive Republican presidential nominee Donald Trump swung back hard at the PGA Tour on Wednesday for moving a golf tournament from his course in Miami to Mexico, and he sounded an ominous warning about how he would respond to such decisions as president.

For Trump, it marked the latest instance of singling out a person, institution or industry he claimed was menacing him unjustly. It also raised new questions about how far he would be willing to go as president to punish his foes. Last week, Trump criticized U.S. District Judge Gonzalo Curiel — who is hearing a fraud case against now-defunct Trump University — with deeply personal and racially tinged language. In a combative news conference Tuesday, Trump said that as president, he would not back down from fierce criticism of journalists he thinks are covering him unfairly.

The PGA Tour announced Wednesday that it was moving a tour date of its elite World Golf Championships from South Florida to Mexico City, beginning in 2017.

"Can you believe it?" Trump asked the crowd at a rally here Wednesday evening. "Think of it: They moved the PGA Tour — moved the World Golf Championship — from Miami, where they're furious, to Mexico City. Not good."

He continued: "But that's okay. Folks, it's all going to be settled, you vote for Donald Trump as president. If I become your president, this stuff is all going to stop."

Trump also expressed annoyance at other companies moving parts of their operations to Mexico, as he has throughout the campaign. In addition, he reiterated his commitment to building a wall along the U.S.-Mexico border.
