WASHINGTON — While preparing to announce his economic team, Donald Trump said Wednesday that he and his children will hold a "major news conference" on Dec. 15 to discuss separation from his various business interests.

Trump made the announcement the same day he is expected to name key members of his economic team, tapping hedge fund manager and campaign aide Steve Mnuchin as secretary of the Treasury and billionaire investor Wilbur Ross as secretary of Commerce.

Confirming his appointment in an interview with CNBC, Mnuchin said his priority is cutting taxes, particularly corporate taxes.
