On Tuesday the Miami New Times released a report alleging that Yankees slugger Alex Rodriguez purchased human growth hormone and other banned substances from an “anti-aging” clinic in Miami called “Biogenesis,” which is now closed. The Times also names several other big league players in the report as well as a man named Anthony Bosch who ran the clinic and reportedly kept sloppy records. CNN has not been able to reach Bosch for comment and the DEA would not comment on whether Bosch or Biogenesis are being investigated.

This morning fmr. Senator George Mitchell, who authored the famous “Mitchell Report” on doping in baseball in 2007 joins “Starting Point.”

Mitchell says the unauthenticated and “dramatic” report raises questions about why someone would keep a journal with the baseball players real names because “it not only implicates the players… it implicates him.” He says the records also name players who have “previously been implicated and after some periods of denial have been admitted they used them.”

Mitchell says sports industries are facing a constant battle and trying to play catch-up with a “large illicit industry [of] people engaged in making these drugs for profit.” He adds that Major League Baseball in particular faces a lot of problems with doping because they’re a private organization and “they don’t have the power of government to compel testimony. So if a person won’t speak to them or won’t give them records voluntarily it takes a lot of sort of hard work to get to building a case and sometimes impossible.”
