Elizabeth Warren tells 'sore loser' Trump to put on his 'big boy pants' and cut the ‘creepy bullying’
Elizabeth Warren (C-SPAN/screen grab)

It's been awhile since Senator Elizabeth Warren (D-MA) went on a tweet storm against Donald Trump, but she was back at it on Wednesday when she tore apart his claim that the presidential election was "rigged" against him.

In it, Warren says that Trump is losing this election because voters can see through his "creepy bullying" -- not because of any "voter fraud."

"Anyone with children knows that whining about imaginary cheating is the last refuge of the sore loser," she writes. "You're losing fair & square. Put on your big-boy pants because this is what accountability looks like."

Warren then goes on to note that unsupported claims of voter fraud have been a staple of Republican politicians stretching back years -- in other words, this "rigged election" talk didn't actually start with Trump.

"It's a longtime argument by the GOP to delegitimize the Democrats," she writes.
