After offering the Dietary Supplement Safety Act of 2010, S. 3002, last month to more closely regulate and restrict the supplement industry, Arizona Senator John McCain reportedly has withdrawn his support for the bill and will now work with Senator Orrin Hatch of Utah on a revised legislative initiative.  McCain’s bill was applauded by anti-doping agencies but was perceived as excessively and unnecessarily onerous on industry.  Hatch had expressed “serious concerns” about the bill in a March 4 letter to Sen. McCain.  A timeline for the new bill is not set.
