FAIR AND BALANCED... Don't miss the final presidential debate, moderated by Fox News' Chris Wallace, on Wednesday, October 19th at 9:00pm ET on Fox News Channel!

Hours before the third and final presidential debate, Elizabeth Warren took to Twitter to blast Donald Trump's allegations of a "rigged" election.

In recent days, the Republican presidential nominee has alleged that there is widespread voter fraud and that the mainstream media is completely biased against him.

Warren tweeted that Trump isn't losing to Hillary Clinton because the election is rigged, but because he's "run a campaign based on hating women, African Americans, Muslims & immigrants."

"Anyone with children knows that whining about imaginary cheating is the last refuge of the sore loser," Warren wrote.

"You're losing fair & square. Put on your big-boy pants because this is what accountability looks like."
