Reminds me of how his father was arrested at a KKK rally, yet people argued you don't know if he was a member or not, he was just arrested there. Papers at the time had varried information, some reporting all 7 people arrested were in robes. One said 6 were robes, 1 was not, but that person's name was not Trump. Hard to say for certain.
We do know a man named Woody Guthrie wrote a song about Fred Trump in the 50s about him racially segregating his neighborhood and that in the 1970s the U.S. DOJ sued the Trump organization for violating the Fair Housing Act do to their discrimination. At that time the chair was Fred, and the president of the company was a man named Donald Trump, who is now our President.
