Trump apologists are bringing this up as if it offsets what Donald Trump has said, but Hillary Clinton is not currently an office holder, and she is also not on the Democratic Party ticket this year. Joe Biden has said that he will concede defeat if the election returns on the night of November 3rd show that Donald Trump has reached 270 electoral college votes. That renders anything that Hillary Clinton has advised Biden, to be irrelevant. Donald Trump's stance is entirely self-serving and very irresponsible coming from a sitting President. If Donald Trump is serious (and that can be hard to tell with Trump) then his attitude does pose a threat to our democratic system of elections. It is impossible to think anything other than Donald Trump only cares about himself. Donald Trump has never demonstrated that he would act in the best interest of this country, if that act had to be at the expense of his own ambitions.
