Apple CEO Tim Cook listens to U.S. President Barack Obama speak at the Summit on Cybersecurity and Consumer Protection at Stanford University in Palo Alta, California February 13, 2015.
That event, the American Enterprise Institute's annual World Forum, is a conference hosted on a private island off the coast of Georgia.
In addition to those tech leaders, attendees this year included Republican party leaders like Senate Majority Leader Mitch McConnell, former presidential advisor Karl Rove, and House Speaker Paul Ryan.
The World Forum is closed to the press, so it's not clear to what degree the tech leaders actually discussed Trump, whose controversial bid for the Republican nomination in the general election has alienated many in the party.
The report also says Cook got into a debate with Republican Senator Tom Cotton of Arkansas on the subject of Apple's ongoing battle with the FBI and cell phone encryption. Per the report, Cotton was "hostile" towards Cook in support of the FBI to the point where onlookers were "a little uncomfortable."
Still, as the Huffington Post reports, conservative political commentator Bill Kristol sent an e-mail dispatch from the event identifying Trump as "a specter" haunting the World Forum. Notably, Rove reportedly presented findings from a focus group suggesting that the public doesn't see Trump as "presidential."
Business leaders attend events like this all the time, and so it's dangerous to assume their political leanings from their presence - Cook may well have made the trip just to get in to those kinds of arguments. But it certainly shows the political weight that Silicon Valley's top leaders command.
