Instead, Clinton was cleared of charges and Donald Trump has been accused, once again, of anti-Semitism.
Dan Scavino, Trump's social media director, issued a statement saying he sourced the image from an anti-Clinton Twitter feed, and referred to the star as a "sheriff's star". "My father looked at the deals Jared was doing and saw himself in those deals", Ivanka Trump said. The same graphic was later deleted and retweeted with the star of David changed into a circle but the white nationalist hashtag #AmericaFirst added, as if that made it any better. Both Jewish, both members of the media. "Mr. Trump's tweet was seen as a winking promise to this nation's worst and most hateful individuals".
Kushner described Trump as "an incredibly loving and tolerant person" whom he had personally seen "embrace people of all racial and religious backgrounds, at his companies and in his personal life".
The explanations, wrote Schwartz in her public letter, were "inane" and "condescending".
Schwartz called it "blatant anti-Semitic imagery" because she said the six-sided star was obviously a Star of David - long a symbol associated with the Jewish religion. In the most pointed passage, Schwartz demanded: "I'm asking you, not as a "gotcha" journalist or as a liberal, but as a human being: How do you allow this?"
But, Mr. Kushner's relatives aren't happy that he publicized his family's survival struggles. Right now, this hate is directed to one of your employees, but the message applies equally to your wife and daughter.
Kushner, who is Orthodox Jewish, is married to Trump's oldest daughter, Ivanka.
The Times found that Kushner helped Trump recruit a communications director, oversaw the creation of an online fundraising system and is helping him choose a running mate.
Schwartz has never met Kushner but said she hoped her letter would compel him as a Trump adviser to take action.
Rubin - a former mayor of the Israeli city of Shiloh and author of several books on Islamic terrorism - says it's actually Clinton who has displayed anti-Semitic tendencies for many years.
So did Trump send that tweet or his team?
For her part, Schwartz said she doesn't believe Trump is anti-Semitic. The controversy has been given the name "stargate".
It's not the first time the two cousins' families have disagreed.
