There apparently isn't much brother-in-lawly love to be spared in the Trump family.

The president's son Donald Trump Jr. and his son-in-law Jared Kushner are fighting behind the scenes to control President Trump's reelection campaign, "five sources close to the White House" recently told Vanity Fair's Gabriel Sherman. But the feud is nothing new, seeing as Trump Jr. reportedly even suspecs it was Kushner who spilled the beans on his infamous Trump Tower meeting more than a year ago.

Trump Jr., Kushner, and former Trump campaign chair Paul Manafort all met with a Kremlin-linked Russian lawyer in Trump Tower ahead of the 2016 election, after Trump Jr. exchanged emails with the lawyer seemingly showing he expected get dirt on Hillary Clinton. The publication of the "closely guarded secret" caught the entire Trump team off guard, as "no one could figure out how it leaked," a Republican close to the White House told Vanity Fair. But Trump Jr. reportedly went around "telling people Jared leaked it to hurt him," the source continued.

Now Trump Jr. is reportedly experiencing "paranoia about Kushner," and scrambles to clean up gaffes that may give Kushner "any excuses to delegitimize him," a person close to Trump Jr. tells Sherman. Republican National Committee Chair Ronna McDaniel told Vanity Fair that "none of this is true," while the White House did not respond to a request for comment. Meanwhile, here's what Trump Jr. had to say. Kathryn Krawczyk
