WASHINGTON - Donald Trump says he is leaving his businesses before Jan. 20 so he can "focus full time" on being president.

He says on Twitter that his sons Don and Eric, along with other executives, will manage the companies, and adds, "No new deals will be done during my term(s) in office."

Trump had been scheduled to hold a news conference this week on the future of his business empire, but it was postponed until next month. Sean Spicer, a Trump transition team spokesman, said the legal team needs more time to work out the plan for the Trump Organization.

Trump is promising to hold a news conference soon "to discuss the business, Cabinet picks and all other topics of interest. Busy times!"
