WASHINGTON (Reuters) - U.S. President Donald Trump on Saturday rejected an author's accusations that he is mentally unfit for office and said his business career and election victory showed he is "a very stable genius."

Michael Wolff, who was granted unusually wide access to the White House during much of Trump's first year, has said in promoting his book that Trump is unfit for the presidency. He told BBC Radio in an interview broadcast on Saturday that his book is creating "the perception and the understanding that will finally end ... this presidency."
