Former Ron Paul associates: He signed off on those newsletters in the 1990s

But people close to Paul’s operations said he was deeply involved in the company that produced the newsletters, Ron Paul & Associates, and closely monitored its operations, signing off on articles and speaking to staff members virtually every day.

“It was his newsletter, and it was under his name, so he always got to see the final product. . . . He would proof it,’’ said Renae Hathway, a former secretary in Paul’s company and a supporter of the Texas congressman…

A person involved in Paul’s businesses, who spoke on condition of anonymity to avoid criticizing a former employer, said Paul and his associates decided in the late 1980s to try to increase sales by making the newsletters more provocative. They discussed adding controversial material, including racial statements, to help the business, the person said.

“It was playing on a growing racial tension, economic tension, fear of government,’’ said the person, who supports Paul’s economic policies but is not backing him for president. “I’m not saying Ron believed this stuff. It was good copy. Ron Paul is a shrewd businessman.’’…

[Lew] Rockwell was the main writer of the racial passages, according to two people with direct knowledge of the business and a third close to Paul’s presidential campaign. Rockwell, founder of a libertarian think tank in Alabama, did not respond to phone calls and e-mails requesting comment. In 2008, he denied in an interview with the New Republic that he was Paul’s ghostwriter.
