Hillary, go on with your life and try again in three years, "Trump said on his Twitter account, alluding to the 2020 presidential election".
Looking past a network like MSNBC, which all but serves as the campaign arm of the Democratic Party, she denounced Fox News for its partisanship.
On Saturday, Trump tweeted that Clinton was "the worst (and biggest) loser of all time", following a string of recent interviews Clinton has held during her book tour.
Two-time failed presidential candidate Hillary Clinton questioned the legitimacy of the 2016 election in a new interview with Mother Jones. Clinton discussed topics such as voter suppression, Russian interference in the election and the election's overall legitimacy.
Here is President Trump's tweet and the heated reactions.
When asked whether or not she believes the election was legitimate, Clinton said: "I think that there are lots of questions about its legitimacy and we don't have a method for contesting that in our system".
"That's why I've long advocated for an independent commission to get to the bottom of what happened", she said.
The thought process is a continuation of the "weaponized false information" narrative that Clinton blames for her loss to President Donald Trump - along with the Russians and voter suppression.
Trump has repeatedly denied his campaign colluded with Russian Federation and has questioned the US intelligence community assessment that Russian Federation worked to interfere in the presidential election to defeat Clinton and to help Trump.
"I think we've got to stand up regardless of what party, regardless of our own ideological beliefs", she continued.
