U.S. counterintelligence officials are looking into Ivanka Trumps business deal in Vancouver as her security clearance continues to hang in the balance, according to a report.

Ivanka played a key role in hammering out the deal for the Trump International Hotel and Tower in Vancouver, which opened just one month after her father entered the White House.

It remains unclear exactly why Ivankas deal with a Malaysian real estate developer on behalf of Trump Organization has piqued the interest of U.S. counterintelligence, but two sources told CNN the FBI has been looking into both the negotiations and financing of the building.

While Ivanka has been entrusted to represent the U.S. on the international stage, she has not obtained full security clearance one year after she was named senior adviser to the President.

Her husband Jared Kushner notably had his security clearance downgraded this week, while a Washington Post report detailed how officials from at least four countries discussed how they could take advantage of his business dealings and lack of foreign policy experience.

Ivanka played a key role in the $360 million project, which was backed by the Canadian-based development company Holborn Group.

The company is run by Joo Kim Tiah and financed by his father Tony Tiah Thee Kian, a wealthy Malaysian tycoon who has broken securities laws and made false statements to the Kuala Lumpur stock exchange.

Both Ivanka and Joo Kim said they worked closely together on the project, and Trump Organization received more than $5 million in royalties in the licensing deal, according to President Trumps financial disclosure form in June.

The 63-story tower attracted foreign investors, who made up 10% of the buyers. At least one had links to the Chinese government, according to the Vancouver Sun.

It remains unclear whether the deal will affect Ivankas security clearance, or be of any interest to the Mueller investigation into the Trump campaigns possible links to Russia.

Peter Mirijanian, a spokesman for Ivanka Trump’s ethics counsel, said, Nothing in the new White House policy has changed Ms. Trump’s ability to do the same work she has been doing since she joined the Administration.”

A spokesperson for Trump Organization said the companys involvement was limited to licensing and management, and played no role in the financing or sale of the units.
