From Wikipedia:
"Hatch's son Scott is a named partner and registered lobbyist at Walker, Martin & Hatch LLC, a Washington lobbying firm. The firm was formed in 2001; the other two partners are Jack Martin, a staff aide to Senator Hatch for six years, and H. Laird Walker, who has been described as a close associate of the senator's.[21] In March 2003, the Los Angeles Times quoted Senator Hatch as saying that the firm was formed with his "personal encouragement" and that he saw no conflict of interest in championing issues that helped his son's clients.[22]
Hatch has legislated for dietary supplements to be governed outside of the realm of drugs and food additives. Utah, his constituency, is considered the "Silicon Valley" of the supplement industry. When the FDA was reviewing the adverse effects of ephedra, Hatch defended the supplement industry. At the time, Walker, Martin & Hatch LLC were being paid, by companies with interests in ephedra manufacturing, for lobbying Congress.[22]
In March 2009, the Washington Times reported that the pharmaceutical industry, which has "long has benefited from Sen. Orrin G. Hatch's legislative efforts", had previously undisclosed connections to Hatch. Five pharmaceutical companies and the industry's main lobbying group, Pharmaceutical Research and Manufacturers of America (PhRMA), wrote checks in 2007 totaling more than $170,000 to the Utah Families Foundation, a tax-exempt charitable foundation which Hatch helped start in the 1990s and had vigorously supported since. Walker, Martin & Hatch LLC was paid $120,000 by PhRMA in 2007 to lobby Congress on pending U.S. Food and Drug Administration legislation."
Too bad they won't go after him for things he's already done. They probably just don't want to bring it up as they're waiting for their turn to do the same thing.
