WASHINGTON (AFP) - Donald Trump's son-in-law and top aide Jared Kushner has been registered to vote as a woman for eight years, US media reported.
Voter information records held by New York show the presidential adviser - whose portfolio includes everything from seeking peace in the Middle East to reining in the opioid crisis in the United States - was registered as "female".
The screenshot, published by Wired, is not the first time the young statesman has fallen foul of bureaucracy.
Kushner, who is married to Trump's daughter Ivanka, also filled out paperwork for his White House security clearance wrongly and had to refile it repeatedly, CBS reported.
Prior to 2009, Kushner's New Jersey voter registration noted his gender as "unknown", according to The Hill news site.
Kushner, the scion of a wealthy property-owning family, is one of a number of Trump's inner circle previously found to have been registered to vote in more than one state during last year's election, the Washington Post has reported.
Others include ex-White House press secretary Sean Spicer and ex-lead strategist Stephen Bannon.
Multiple registrations were pointed to by the president as a sign of purported widespread voter fraud in the 2016 election. Trump said millions of people illegally cast votes for Hillary Clinton but has never substantiated his claim.
Kushner - a person of interest in the ongoing probe into Russian interference in the US election - has also recently been accused of using private e-mail accounts to conduct government business.
Trump's insurgent presidential campaign was galvanised by supporters' demands that Clinton be jailed for her use of private e-mail servers while Secretary of State.
