Kushner, who is President Trump’s son-in-law, and a close adviser, also did not disclose loans on several properties that total more than $1 billion, the Journal reported.
The investment in the startup Cadre makes Kushner a partner with Goldman Sachs.
An attorney for Kushner told the newspaper that he disclosed his ties to BFPS Ventures LLC, which includes Cadre, though his forms did not specifically mention the startup.
The attorney said a revised disclosure will include the stake in Cadre once officials approve the form. Kushner founded the startup with his brother, Joshua, and another friend in 2014. George Soros, known for his Democratic fundraising, is another Cadre investor.
The disclosures also show that Kushner has ties to multiple foreign banks.
Kushner in early January stepped down as CEO of his family’s company, Kushner Companies, before becoming a senior adviser to the president.
