US President Donald Trump's senior adviser and son-in-law Jared Kushner will make a rare public appearance on Sunday, when he partakes in a keynote conversation at the Brookings Institution's annual Saban Forum in Washington, D.C.

Kushner, 36, has been tasked by his father-in-law to lead the White House's efforts toward forging an Israeli-Palestinian peace accord.

He will discuss those efforts and the administration's broader Middle East approach with Haim Saban, the Israeli-American media mogul who hosts the prestigious confab in collaboration with Brookings.

Saban is also a major Democratic donor and has financially backed former secretary of state Hillary Clinton — Trump's 2016 campaign rival — in the past.
