Actor and devout Bernie Sanders supporter Tim Robbins alleged Bernie Sanders has lost multiple primaries due to election fraud and attacked Hillary Clinton ally David Brock on Twitter Monday.

It all started with Robbins tweeting an image claiming that exit polls results prove voter fraud in multiple Democratic contests.

Hey NYTimes, CNN. Are you saying that 2+2=5? Are you really OK supporting a candidate with these numbers?#VoterFraud pic.twitter.com/LrxqLTaKbC — Tim Robbins (@TimRobbins1) April 25, 2016

Hillary supporters soon came to her defense.

@TimRobbins1 You REALLY cannot be suggesting that exit polls are actually exactly accurate or even close to being accurate at times? WOW. — Robert Sandy (@frodofied) April 25, 2016

@TimRobbins1 OMG, go get yourself committed for a bit before it’s too late, you are losing your marbles right before our eyes. — peek a boo (@Run_IsHere) April 25, 2016

@TimRobbins1 Exit polls more reliable than votes? Rigged machines? Ok Mr. Conspiracy theorist.Cause it couldn’t be your guy is just losing! — Laurie Spoon (@LaurieSpoon) April 25, 2016

Robbins gave all of these tweets the same response, alleging the Twitter users work for David Brock’s Correct the Record outfit.

He then tweeted out a rant. (RELATED:Sanders Surrogate: I’m With Monica Lewinsky)
