Ivanka Trump and husband Jared Kushner made $82m last year

US President Donald Trump's daughter and son-in-law made at least $82 million in outside income while serving as senior White House advisers last year thanks to investment deals from companies they had previously led.

Ivanka Trump reported $3.9m from her stake in the Trump International Hotel in Washington, as well as more than $2m in severance pay from the Trump Organisation, The Washington Post said, citing financial disclosure forms released on Monday.

Her husband Jared Kushner earned more than $5m from the Kushner Cos. apartment complex Quail Ridge in New Jersey.

Mr Kushner also declared income from dozens of companies linked to his family's real estate business. In all, he took in at least $70m, the newspaper said.

The couple, who have put their daily management of their companies on hold while they serve at the White House, have still managed to obtain huge amounts of income from other companies during their short time in public office.

The newspaper estimated Mr Kushner's assets at $179m to $735m last year, compared to between $55.3m and $75.6m for Mr Trump's daughter, noting that the Office of Government Ethics uses broad ranges for assets and liabilities.

Some of the couple's assets were listed jointly.

In July last year, the time of their last financial disclosure, the couple reported joint income of at least $19m from business ventures and another $80m in real estate and other revenues between January 2016 and early last year.
