Sen. Elizabeth Warren (D-Mass.) blasted Donald Trump for doubling down on his repeated suggestion that the November election will be rigged, telling him on Twitter to stop complaining and put on his “big boy pants” ahead of the third presidential debate.

“Give me a break, @realDonaldTrump. You’re not losing because it’s rigged,You’re losing because we see through your creepy bullying,” Warren tweeted. “Anyone with children knows that whining about imaginary cheating is the last refuge of the sore loser,” she wrote in another tweet.


Trump doubled down on his predictions of a “rigged” election on Monday night at a rally in Wisconsin when he told the crowd: “Remember, we are competing in a rigged election.They even want to try and rig the election at the polling booths, where so many cities are corrupt and voter fraud is all too common.”

Warren continued her tweetstorm, widening her attack to the Republican Party — saying Trump isn’t alone in suggesting the election could be compromised.

“It’s fascinating, @realDonaldTrump: ‘voter fraud’ only seems to plague places where lots of people might vote for @TheDemocrats.” she tweeted.

“But @realDonaldTrump didn’t come up with the ‘rigged’ election himself. It’s a longtime effort by the @GOP to delegitimize @TheDemocrats.”

Trump’s campaign manager, KellyAnne Conway seemed to break with her candidate Wednesday, telling MSNBC that she does not believe the election will be rigged or that there is widespread voter fraud. She instead suggested there’s a “larger conspiracy” working against the GOP nominee.
