In 1927, Donald Trump’s father was arrested after a Klan riot in Queens

On Memorial Day 1927, brawls erupted in New York led by sympathizers of the Italian fascist movement and the Ku Klux Klan. In the fascist brawl, which took place in the Bronx, two Italian men were killed by anti-fascists. In Queens, 1,000 white-robed Klansmen marched through the Jamaica neighborhood, eventually spurring an all-out brawl in which seven men were arrested.

One of those arrested was Fred Trump of 175-24 Devonshire Rd. in Jamaica.

This is Donald Trump's father. Trump had a brother named Fred, but he wasn't born until more than a decade later. The Fred Trump at Devonshire Road was the Fred C. Trump who lived there with his mother, according to the 1930 Census.
