Filmmaker Michael Moore expressed alarm on Friday regarding how close Donald Trump is to a potential presidential victory, Mediaite reported.

“This is the man now tied or leading in the polls,” Moore posted on Twitter, linking to a 2013 tweet from the GOP presidential nominee suggesting that President Barack Obama had someone killed over his birth certificate:

Yes, this is the man now tied or leading in the polls… #getbusypeople #Munich33 https://t.co/Q485ZuIEcK

I'd never before seen this Trump tweet, implying the White House murdered a man to keep Obama's birthplace secret. pic.twitter.com/o82mDEsUSz

Trump spewed racial hate for yrs insisting Obama was an African but not an American. He ignited the fire of hate we will now have to put out

Moore also spread a similar sentiment from comedian Patton Oswalt, and noted Trump’s public involvement in the “Central Park Five” case, in which five young black men were wrongfully convicted for raping a white woman in New York City.

Again, this is the unstable, vengeful douche who wants to control our nuclear arsenal. https://t.co/Bd1vjVvoVm

Never forget: Trump LED a racist lynch mob & got 5 youths WRONGFULLY convicted in the CentralPark jogger case. They spent 6-13yrs in prison!

According to Moore, “nothing short of a 50-state sweep” by Democrat Hillary Clinton this November would “make up” for Trump’s anti-minority rhetoric.

Nothing short of a 50-state sweep & repudiation will make up for the hate he has spewed at Black, Hispanic and Muslim America. #Berlin1933
