One of President Donald Trump's top White House aides resigned Wednesday following allegations of domestic abuse leveled against him by his two ex-wives.

Staff secretary Rob Porter said in a written statement that allegations that became public this week are "outrageous" and "simply false." Porter said photos published of his former spouses — in which one appears to have a black eye — were "given to the media nearly 15 years ago and the reality behind them is nowhere close to what is being described."
