Ron Paul signed off on and was deeply involved in racist and homophobic writings in the newsletters he published in the 1980s and 90s, three people claim.

Paul has denied any knowledge of the contents of the newsletters.

However, The Washington Post quotes three people as saying that Paul closely monitored his company Ron Paul & Associates, which produced the pamphlets.

“It was his newsletter, and it was under his name, so he always got to see the final product. … He would proof it,” Renae Hathway, a former secretary in Paul's company, told the paper.

Paul denied any involvement with the newsletters in an interview with CNN: “I've never read that stuff. I've never read – I came – was probably aware of it 10 years after it was written.”

The articles were often tinged with racist, anti-Semitic and anti-gay overtones.

“Homosexuals, not to speak of the rest of society, were far better off when social pressure forced them to hide their activities,” read the June 1990 edition of the Ron Paul Political Report.

The newsletters were “playing on a growing racial tension, economic tension, fear of government,” an unnamed sourced told the paper. “I'm not saying Ron believed this stuff. It was good copy. Ron Paul is a shrewd businessman.”

Paul voted in favor of repealing “Don't Ask, Don't Tell,” and while the Texas congressman does not support gay marriage, he opposes a federal amendment which would define marriage as a heterosexual union.
