Republican presidential frontrunner Donald Trump quoted and linked to an openly neo-Nazi Twitter account on Friday.

Trump’s tweet can be seen above.

Trump quoted and shared a posting from the account @WhiteGenocideTM that mocked his opponent former Florida Gov. Jeb Bush. The message featured a Photoshopped image of Bush standing in front of Trump’s Manhattan headquarters, Trump Tower, with a cardboard sign saying, “Vote Trump.”

The account, which Trump featured on his personal Twitter page, is littered with neo-Nazi content. In the user’s profile, there is a link to a website for an admiring documentary describing Adolf Hitler as “a god.” The tweet pinned at the top of the @WhiteGenocideTM account includes images of people identified as Jews covered with the common white supremacist slur “mud” and yellow Stars of David used during the Holocaust.

@WhiteGenocideTM’s avatar features a picture of the deceased American Nazi Party leader George Lincoln Rockwell. The profile background contains the phrase “Get the f*** out of my country.” The user also posted tweets praising Hitler.

Trump’s campaign did not immediately respond to a request for comment about the tweet. The user behind @WhiteGenocideTM also didn’t respond to Twitter messages from Yahoo.

As of this writing, Trump’s tweet quoting the neo-Nazi account had been live for more than six hours.
