U.S. President-elect Donald Trump said on Tuesday that his son-in-law Jared Kushner could help make peace between Israelis and Palestinians.

Speaking to the New York Times in New York, Trump said he "would love to be the one who made peace with Israel and the Palestinians," adding that it would be a "great achievement," according to a reporter's tweets.

On Wednesday, Trump requested top secret security clearance for Kushner, according to an NBC News report. The request for clearance was unprecedented and would allow Kushner to sit in on Trump's presidential daily brief, despite not being an official member of the White House staff.

Kushner, a real-estate developer and publisher of the New York Observer, served as a key adviser in Trump's successful presidential campaign - including to help draft Trump’s speech to AIPAC last summer.

Throughout the campaign, Trump delivered contradictory messages on the subject of Israeli-Palestinian peace. In one instance, he said he will be "neutral" in his attempt to promote the peace process, a remark that brought criticism from Israel's supporters in the U.S. On another occasion, he said that he will not exert any pressure on Israel and will even allow as much settlement building as it wishes.

Earlier in November, Trump told the Wall Street Journal he will try and achieve peace between Israel and the Palestinians in order to bring an end to what he called "the war that never ends."

“As a deal maker, I’d like to do the deal that can’t be made. And do it for humanity’s sake,” he added.

In his meeting with the New York Times reporters, Trump also condemned an alt-right conference in Washington held over the weekend during which some members performed a Hitler salute and yelled "Hail Trump!" after a speech about white nationalism.
