Donald Trump promised Wednesday to ‘remove’ himself from his businesses and said he will announce details in two weeks about how he’ll avoid conflicts of interest when he is president.

Trump used his favorite method of communicating with the public — Twitter — to announce plans for a “major news conference” on Dec. 15 to discuss plans to leave the Trump Organization.

His adult children, whom he has said he will put in charge of the company, will be a part of the news conference.

Trump owns or has a position in more than 500 companies, according to a CNN analysis. That includes about 150 that have done business in at least 25 foreign countries, including Turkey, Qatar and Saudi Arabia.

There have been growing questions about the potential conflicts of interest posed by Trump’s continued business interests and his role as president. A poll by CNN found that 6 in 10 Americans believe Trump is not doing enough to address conflicts of interest.

His tweets said he is not mandated to leave his business by law, but that “I feel it is visually important, as President, to in no way have a conflict of interest with my various businesses.”

Trump also said he is doing so “in order to fully focus on running the country in order to make America great again.” Legal documents are being crafted which take him completely out of business operations, he claimed. “The Presidency is a far more important task!”
