WASHINGTON, May 16 (Xinhua) -- U.S. President Donald Trump had at least 434 million U.S. dollars in revenue last year, according to his latest financial disclosure report released on Thursday.

The report, required to be filed annually with the Government Ethics Office, covers the president's finances for 2018, his second year in office.

The report shows that in 2018 Trump had a minimum of 434 million dollars in revenue from all sources, which included various businesses such as hotels, golf courses, and book revenue.

It is impossible to determine the exact amount the president earned because the filing includes ranges of revenue for some categories.

In 2017, Trump reported a minimum of 452 million dollars in revenue.

Thursday's disclosure comes as the Trump administration faces a Friday deadline to respond to a subpoena from House Democrats for six years of tax records.
