Here’s one place you won’t see ads featuring Donald Trump: BuzzFeed.

On Monday, the media company’s chief executive told employees that the presumptive Republican presidential nominee’s campaign is “directly opposed to the freedoms of our employees in the United States and around the world.”

CEO Jonah Peretti explained that the company doesn’t like to turn away revenue that funds its work, but in some cases exceptions must be made.

“We don’t run cigarette ads because they are hazardous to our health, and we won’t accept Trump ads for the exact same reason,” Peretti said.

He said in some cases — like Trump’s proposed ban on Muslim immigration to the U.S. — the Republican’s policies “would make it impossible for our employees to do their jobs.”

Peretti’s email said BuzzFeed and the Republican National Committee signed an agreement back in April, in which the RNC would spend a “significant amount” on ads.

An RNC official told MarketWatch that no money has changed hands, and that the ad reservation with BuzzFeed was less than 1% of the total reservations the committee made across dozens of platforms. The RNC reserved $150 million in ads across platforms.

Early Monday afternoon, RNC Communications Director Sean Spicer said the committee wasn’t planning to put up ads on BuzzFeed anyway.

“Space was reserved on many platforms, but we never intended to use BuzzFeed,” Spicer said in a statement.

In a reference to Democratic contender Hillary Clinton and BuzzFeed, Spicer added: “Although it is ironic that they have not ruled out taking money from a candidate currently under investigation by the FBI.” The FBI is investigating whether classified information was transmitted through Clinton’s private email server when she was secretary of state.

Trump, meanwhile, has been the biggest recipient of free advertising this campaign season. Over the past 12 months, he has gotten the equivalent of more than $3 billion in free ads, according to the latest data from tracking firm mediaQuant. He got nearly $640 million of that in May alone.
