WASHINGTON, Nov. 18 (Xinhua) -- U.S. President Donald Trump on Saturday denounced allegations of Hillary Clinton who questioned the legitimacy of his victory in last year's presidential election.

Calling his Democratic presidential rival the "worst of biggest loser of all time," Trump tweeted that "She just can't stop, which is so good for the Republican Party."

"Hillary, get on with your life and give it another try in three years," he added.

Trump made the remarks a day after Clinton told media that the "Russian meddling" in the 2016 presidential campaign creates questions over the "legitimacy" of his victory.

Also on Friday in another media interview, Clinton lashed out at Trump and Alabama Republican Senate nominee Roy Moore for not taking responsibilities for sexual assault allegations made against them.

She said in an interview with WABC radio that by contrast Senator Al Franken, who was accused of forcibly kissing and groping a female broadcaster, had accepted "responsibility" and apologized to the victim.

But the White House argued that there is a clear difference between Franken's case and that of the president.

"I think in one case specifically, Senator Franken has admitted wrongdoing, and the president hasn't," White House Press Secretary Sarah Sanders told a press briefing Friday. "I think that's a very clear distinction."

In last year's presidential election, Clinton won the popular vote but Trump prevailed in the Electoral College as a result of narrow wins in U.S. states of Pennsylvania, Michigan and Wisconsin.
