By the numbers: How Trump properties profited from his presidency

Republican political campaigns and U.S. government agencies have spent more than $16 million on Trump properties for events, lodging, meals, rounds of golf and more since Donald Trump launched his presidential campaign in 2015, according to data collected by ProPublica.

Why it matters: Government ethics watchdogs have claimed that this kind of spending reveals a presidential conflict of interest — or at the very least, bad optics. In May, a federal judge allowed a lawsuit accusing Trump of breaking the Constitution's Emoluments Clause, which bans improper payments from individual states and foreign governments, to move forward. A final ruling is expected in July.
