(JTA) — President-elect Donald Trump said that if his son-in-law Jared Kushner cannot produce peace in the Middle East, then “nobody can.”

Trump referenced Kushner, a Jew who married Trump’s eldest daughter Ivanka after her Orthodox conversion to Judaism, during a VIP reception and candlelight dinner Thursday night at Union Station in Washington D.C. ahead of Trump’s inauguration Friday.

“All my life I’ve been hearing that’s the toughest deal in the world to make. And I’ve seen it. But I have a feeling Jared’s going to do a great job,” Trump said. Addressing his son-in-law, he also said: “If you can’t produce peace in the Middle East, nobody can.”

Trump has named his son-in-law a senior White House adviser. Kushner, a wealthy businessman and real estate developer, served as a top confidante to Trump during the campaign. “I sort of stole her husband,” Trump quipped about his daughter and Kushner on Thursday.

Trump’s endorsement of Kushner for Middle East peace negotiator follows a series of previous statements in which Trump expressed confidence in Kushner’s abilities in that capacity.

“Jared is such a good kid and he’ll make a deal with Israel that no one else can — you know he’s a natural, he’s a great deal, he’s a natural — you know what I was talking about, natural — he’s a natural deal-maker — everyone likes him,” Trump said in ab interview earlier this month in The Times of London and Bild.

Tens of thousands of people are preparing a march on Saturday in the capital in favor of women’s rights. The march is seen by many organizers as a protest against Trump’s rhetoric during the campaign, when he was accused of speaking denigratingly about women and Latinos.

The march will set out from downtown D.C. on Saturday morning and advocate for women and minorities, including support for reproductive and civil rights, environmental regulation, and protections for immigrants and the LGBT community.

The Sixth and I synagogue in Washington D.C. will host Jewish groups and individuals participating in the march for activities and prayers.
