Thanks to Megan for pointing me to this, which contains a link to this article:
Financial records from 1985 and 2001 show that Rockwell, Paul’s congressional chief of staff from 1978 to 1982, was a vice president of Ron Paul & Associates, the corporation that published the Ron Paul Political Report and the Ron Paul Survival Report. The company was dissolved in 2001. During the period when the most incendiary items appeared—roughly 1989 to 1994—Rockwell and the prominent libertarian theorist Murray Rothbard championed an open strategy of exploiting racial and class resentment to build a coalition with populist “paleoconservatives,” producing a flurry of articles and manifestos whose racially charged talking points and vocabulary mirrored the controversial Paul newsletters recently unearthed by The New Republic. To this day Rockwell remains a friend and advisor to Paul—accompanying him to major media appearances; promoting his candidacy on the LewRockwell.com blog; publishing his books; and peddling an array of the avuncular Texas congressman’s recent writings and audio recordings.
Of course, now Paul’s Congressional Chief of Staff is coming out and saying it was indeed Rockwell who was responsible for the letters. Trying to fan the flames of racial bigotry is quite despicable, and while I leave open the possibility that Ron Paul is not himself a racist, I have no problem with judging the man by the company he keeps.
