Ivanka Trump, Jared Kushner worth up to $740 million, part of an ultra-wealthy White House staff

The White House released financial disclosures for several top Trump staffers.

The financial information on the president's daughter and son-in-law is among a trove of financial disclosure forms that confirm the astounding wealth of senior staff in the White House, who have an estimated combined net worth of at least $12 billion. Ivanka Trump, who just this week became a federal employee as an assistant to the president, has yet to file her own financial disclosure information. Kushner is a senior adviser to Trump.

Ivanka Trump and Kushner's continued vast business holdings led one ethics expert to say the couple should recuse themselves from involvement in any government matters that could affect their business interests.

Kushner, in accepting the White House job in January, pledged to divest from all his common-stock and foreign investments. He resigned from 260 business entities, sold off 58 businesses and put most of his financial holdings into a trust overseen by his mother, officials have told ABC News.

"The president has brought a lot of people into this administration and this White House in particular who have been very blessed and very successful by this country," Spicer said. "It speaks volumes to the desire for a lot of these people to fulfill the president’s vision and move the agenda forward that they are willing to list all of their assets, undergo this public scrutiny, but also set aside a lot."

Trump's chief economic advisor, Gary Cohn, formerly chief operating officer of Goldman Sachs, earned at least $48.3 million in income in 2016, and holds assets valued at $252 million and $611 million.

Spicer was asked by media Friday about the contrast between the financial disclosures on White House senior staff and President Trump's continued refusal to release his tax returns.

"That’s apples and oranges," Spicer said. The disclosure forms on senior staff "are required by law."
