"Every president is tested by world events, but Donald Trump thinks about how his golf resort can profit from them," a narrator says.

The ad then shows Trump predicting that more people would visit Turnberry, his golf course in Scotland, if the value of the pound plummeted.

"Brand new sprinkler system, the highest level," Trump said in another clip in the ad while visiting his Scotland golf course.

"In a volatile world, the last thing we need is a volatile president," the narrator says at the end of the ad.

After British voters chose to leave the European Union, Trump applauded the people who he said "took their country back." He said people all over the world are "angry," and predicted other places would similarly reject the status quo.

Clinton's campaign blasted Trump for cheering and celebrating the Brexit vote, as the decision sparked a sharp decline in the stock market.

"He patted himself on the back and boasted about the money that his golf courses would make as a result of the turmoil," Clinton adviser Jake Sullivan said in a statement.

The vote created uncertainty in the global financial markets and the value of the pound immediately plummeted in response.

Trump early Sunday hit back, tweeting Clinton is "spending Wall Street money" on an ad after her "bad judgement call" on Brexit.
