A Metro platform at Union Station was littered with printouts promoting a Holocaust-denying film Sunday.

Metro rider Alex Marshall said he found the information taped to signs at the station. He tweeted photos showing the printouts, which contained links to anti-semitic videos, strewn about the platform.

A YouTube description for one of the videos says “Unlike the demonic portrait that the ‘allies’ painted of him, Hitler was beloved by his people, he wanted nothing but peace, and never ordered the extermination of a single Jew.”

The Nazi-led Holocaust killed 6 million Jews and millions more Communists, gay people, Gypsies, Poles and people with disabilities.

Metro spokesman Ron Holzer said janitorial staff were sent in to clean up the platform. He said the printouts constituted free speech, and police were not notified. No further action was taken, he said.

Marshall alerted Metro staff to the printouts through Twitter.

“I picked them up and [put] them where they belong: in the trash,” he tweeted. “I can’t believe this is happening in 2016.”
