U.S. President Donald Trump filed his annual financial disclosure form this week with the Office of Government Ethics, the U.S. government's ethics watchdog.
Under U.S. law, all top government officials are required to file annual financial disclosure documents with the agency.
In Tuesday's 92-page filing, Trump acknowledged that he'd reimbursed his personal lawyer, Michael Cohen, last year for more than $100,000 for unspecified expenses incurred in 2016.
Trump’s lawyers have previously said the president reimbursed Cohen for $130,000 that Cohen paid to an adult film star to keep her quiet about a sexual tryst she said she had with Trump 10 years earlier. Trump has denied having the tryst but recently confirmed reimbursing Cohen to stop “false and extortionist accusations” about it.
The financial disclosure did not say why Trump had not listed the payment in his previous financial filing, but the ethics agency said the reimbursement constituted a loan that should have been reported.
That has set off a firestorm of criticism and calls for an investigation into whether Trump violated federal law by omitting the payment from his 2017 disclosure.
The controversy has overshadowed other details in Trump's financial disclosure, which is the only publicly available snapshot into the president's finances — his debts, assets and income from dozens of companies and partnerships around the world.
Here are six noteworthy takeaways from the report:
Golf losses. Trump, an avid golfer who frequently visits his golf courses, sometimes in the company of world leaders, listed 17 golf companies in his disclosure form, with 13 reporting losses. Overall, golf-related revenue plunged to $210 million from nearly $300 million from the previous reporting period. However, the president's struggling golf courses in Turnberry, Scotland, and Doonbeg, Ireland, improved their earnings, with income at the Turnberry property growing to more than $20 million from $14 million. Trump plans to travel to Scotland during his visit to Britain this summer.
