The FBI is looking into a business deal in Canada made by President Trump’s daughter and adviser, Ivanka, as part of checks to determine whether she should receive full security clearance.

The news station explained it was regular practice to ensure those receiving clearance were not susceptible to pressure from abroad.

According to CNN, a US official said the FBI was examining the Trump International Hotel and Tower in Vancouver.

Although the Trump Organisation does not own the building, it received $5 million [£3.6 million] in royalties from a Canadian development company owned by a wealthy Malaysian family.

Peter Mirijanian, a spokesman for Ms Trump, said that CNN was wrong that any “red flag or problem has been raised with respect to Ms Trump or her clearance application. 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.”

Last week her husband Jared Kushner’s security clearance was downgraded from top secret to secret.

Michael Wolff, in his book Fire and Fury: Inside the Trump White House, claimed that Ms Trump nursed the ambition of becoming the USA’s first female president.
