President-elect Donald Trump said Wednesday that he's leaving his business empire to focus on being the nation's 45th president, bowing to pressure to avoid potential conflicts of interest between governing and profiting in the private sector.

"I will be leaving my great business in total in order to fully focus on running the country in order to make America great again," he tweeted in a series of missives sent before dawn.

"While I am not mandated to do this under the law, I feel it is visually important, as president, to in no way have a conflict of interest with my various businesses."
