Kushner married Trump's pride and joy Ivanka in 2009 at a star-studded wedding at a Trump golf club in New Jersey after she converted to Judaism for him.
He has not been given an official position within the Trump administration, but Mr Kushner has been named alongside three of Mr Trump's children in the transition team, and he is said to have the President-elect's ear.
A security clearance for the president-elect's family would raise questions about possible conflicts of interest, considering his children's involvement in a business network Trump has arranged and called a "blind trust".

In a speech filled with memorable quotes, he reminded the world that in democracies, "The most important title is citizen". He says that's as long as people retain faith in democracy and don't waver from democratic principles.
Donald Trump's former campaign manager said Tuesday that any inquiries into getting security clearances for President-elect Donald Trump's adult children would have been made "very informally". "That's not something I'm expecting right now", they added. Mr Kushner is believed to have been one of the leading voices who kept Mr Christie off Mr Trump's presidential ticket. Instead, he likes to operate behind the scenes and has gradually become the president-elect's closest and most trusted advisor - a position he seems determined to carry into the White House, considering how Trump took the unprecedented step of requesting security clearance for his son-in-law.
Despite this, Kushner and wife Ivanka are set to hold significant roles in Trump's transition as president. Klem said that Marker "was following customary protocol" and was "still making adjustments post-election. I'm exhausted of seeing a Ape in heels", Taylor said.
Kushner, like Trump, attended an Ivy League school, grew his father's real estate business and expanded his own net worth exponentially.
Rep. Elijah Cummings (D-Maryland), ranking member of the House Committee on Oversight and Government Reform, wrote a letter to new White House Chief of Staff Reince Priebus asking for an explanation of the reported request and expressing his concerns.
Another transition official pushed back on the reporting, which was first published by CBS News.
