Donald Trump's net worth drops $800m in last year
US presidential candidate Donald Trump has lost as much as $800m during the last year, according to an investigation carried out by Forbes.
Trump has repeatedly cited his business prowess as a reason for him to be elected to the oval office ahead of Democrat rival Hillary Clinton.
Clinton has continually accused him of a lack of transparency surrounding his finances however, calling on him to release his tax returns. Decades of precedent have seen all candidates release their federal taxes, but Trump has so far refused.
Forbes' investigation into Trump's finances has reported that his net worth stands at $3.7bn, a figure $800m shy of his valuation from a year ago.
The magazine investigated 28 of Trumps's assets and found that 18 of them had decreased in value over the year. Those to decline included Trump Tower in New York City which lost $159m of its value in a cooling period for the real estate market there.
The tycoon has vowed to get rid of trade deals with developing nations in order to focus on US industries, as well as promising to force Mexico to build a border wall.
Trump said during a televised election debate on Monday that "you don't learn that much from tax returns".
The two will go head-to-head twice more in televised debates in October, as the candidates enter the final stretch before the crucial election on 8 November.
