The Observer, a news site owned by President-elect Donald Trump’s son-in-law Jared Kushner, posted an op-ed calling for an FBI investigation into the “political thuggery” of anti-Trump protests taking place in the wake of the presidential election.

Throughout the 2016 presidential campaign, Donald Trump threatened and criticized protesters during campaign events, saying of one that he’d like to “punch him in the face” and reminiscing of the “good old days” when protesters would be “carried out on a stretcher.” Trump even threatened to “start pressing charges” against protesters after demonstrations during a Chicago campaign rally caused the event to be postponed after fights broke out between demonstrators and Trump supporters. Now Trump supporters want an FBI investigation of of anti-Trump protests.

On December 2, the Observer posted an op-ed written by University of Texas in Austin adjunct professor Austin Bay, which called for FBI Director James Comey to conduct a “detailed investigation” into the anti-Trump protests taking place across the country. To make his point, Bay invokes “Kristallnacht,” a 1938 incident in which Nazis burned synagogues, vandalized Jewish-owned businesses and homes, and resulted in 30,000 Jewish men being sent to concentration camps. Bay even cites notorious conspiracy theorist Jim Hoft’s blog post claiming anti-Trump protesters were paid to protest, a claim that gained traction based on a fake news story.

The posting of the op-ed is extremely concerning given the influence Kushner has on his father-in-law. In July, The New York Times reported that Kushner had “become involved in virtually every facet of the Trump presidential operation” and wrote that many viewed him as the “de facto campaign manager.” Following the election, Kushner also explored legal loopholes that would allow him to bypass federal nepotism laws and join the Trump administration in an official capacity:
