President Donald Trump responded to the latest outburst from Hillary Clinton, calling her out as the “worst … loser” of all time.

“Crooked Hillary Clinton is the worst (and biggest) loser of all time,” Trump wrote on Twitter:

Clinton raised questions in a recent interview about the “legitimacy” of the 2016 presidential election and signaled disappointment that the country did not have a way to contest the election results.

Trump urged her to continue complaining about the election results, telling her to run for president again.

“She just can’t stop, which is so good for the Republican Party,” he wrote. “Hillary, get on with your life and give it another try in three years!”
