Washington, Dec 18 (IANS): US President Donald Trump's daughter Ivanka Trump and her husband Jared Kushner have been hit with a lawsuit alleging illegal omissions on their public financial disclosure forms.

The couple, both serving as advisers in the White House, are facing a lawsuit from lawyer Jeffrey Lovitky, who claimed they both didn't include assets from 30 investment funds they were a part of, Politico magazine reported.

The lawyer also alleged Ivanka Trump and her husband didn't identify the income they received from two other investment groups.

Lovitky stated that for several investment funds, Kushner did not list the assets because of a "pre-existing confidentiality agreement".

"The (Ethics in Government Act) does not allow a reporting individual to refuse to disclose the underlying assets of an investment vehicle on the basis that such disclosure would violate a pre-existing confidentiality agreement", the lawsuit read.

"Nor does the EIGA allow a reporting individual to refuse to disclose the amount of income derived from any underlying asset of an investment vehicle on the basis that such disclosure would violate a pre-existing confidentiality agreement," it said.

Kushner has amended his financial disclosure form multiple times since it was filed in March, revealing dozens of assets that were initially left off the form. He has said the assets were "inadvertently omitted."

Kushner and Ivanka Trump were also fined for submitting late filings.

Lovitky had also sued President Trump over his financial disclosure form alleging that he failed to show how responsible he was for debts he listed on a form filed during the 2016 campaign.
