Citizens for the Integrity of Science
Although Milloy's Junk Science Home Page does not disclose its specific funding source, the website, Citizens for the Integrity of Science [in 1999], and the debunked TASSC share the same address at 1155 Connecticut Avenue, NW, Suite 300 in Washington, DC. 
Milloy is an 'adjunct scholar' at the Cato Institute, which has published his books such as Junk Science Judo: Self Defense Against Health Scares and Scams . He is also a columnist for FoxNews.com and runs an organisation called Citizens for the Integrity of Science, (CFIS). Details about CFIS are scant but it appears to have some sort of board, of which only two members, including Milloy, are known. The other is Michael Gough of the Competitive Enterprise Institute (and Cato) who is the co-author with Milloy of Silencing Science (Cato Institute 1998). 
The phone number for junkscience.com is registered to "Advancement of Sound Science Coalition" (a well exposed corporate front group and a former project of the EOP Group) at 1155 Connecticut Ave NW, Suite 300 in Washington, DC. This is the same phone number and address Milloy has used for the Citizens for the Integrity of Science, Junkscience.com, NoMoresScares.com, and of course, the defunct The Advancement of Sound Science Coalition (TASSC). The fax number used on numerous press releases over the years is "an interoffice fax" at 1155 Connecticut Ave NW,. according to a simple internet search.
The internet site, CFIS.org (Citizens for the Integrity of Science), is registered to Steve Milloy's home address in posh Potomac, MD, with Steve Milloy listed as the administrative contact. So who is actually paying for junkscience.com? We don't know, and Milloy has repeatedly refused to disclose his patrons.
CFIS does appear to have some sort of board, though we know of only two members, including Milloy. In a May 11,1999 Freedom of Information Act filed by Citizens for the Integrity of Science posted on the Junkscience web page, Steve Milloy listed himself and Michael Gough of the Competitive Enterprise Institute as "Directors" of Citizens for the Integrity of Science, with TASSC's old 1155 Connecticut address and contact info, which is also Milloy's current business address.

The industry front group Citizens for Integrity in Science should not be confused with The Integrity in Science Database of Scientists and Organizations With Ties to Industry. The database is a project of the Center for Science in the Public Interest, CSPI, a Washington, DC, non-profit active on a variety of food safety issues. CSPI is routinely villified by industry-funded front groups such as Rick Berman's Center for Consumer Freedom.
