In comments to a local Philadelphia radio station Wednesday, Donald Trump Jr. argued that the media was ignoring Hillary Clinton's lies and distortions, and that if his father did the same thing, it would be ''warming up the gas chamber.''
''The media has been her number-one surrogate in this. Without the media, this wouldn't even be a contest. But the media has built her up. They've let her slide on every indiscrepancy [sic], on every lie, on every DNC game trying to get Bernie Sanders out of this thing,'' Trump Jr. said.
He added: ''If Republicans were doing that, they'd be warming up the gas chamber right now.''
A spokesman for Clinton's campaign tweeted the comments Thursday morning, agreeing with a reporter who labeled them a Holocaust joke.
This is hardly the first time allegations of anti-Semitism have crept into the 2016 campaign.
The Trump campaign has previously found itself under fire for using imagery that could be construed as anti-Semitic. In July, Trump tweeted an image with a six-pointed star around the words ''Most Corrupt Candidate Ever!'' Next to the star was a picture of Clinton's face. In the background was a layer of hundred-dollar bills.
The image was taken from a Twitter user who disparaged Muslims, black Democrats and others, yet the Trump campaign argued that the whole thing was being blown out of proportion.
Last month, a Trump foreign policy adviser was accused of making anti-Semitic comments. And throughout the campaign, Jewish reporters have been harassed by Trump supporters who espouse anti-Semitic ideas.
As with all things Trump, Trump Jr.'s comments are questionable enough to cause controversy but oblique enough that defenders claim they had nothing to do with the Holocaust.
