Phil Montgomery will be the new head of Wisconsin's Public Service Commission, which regulates energy, water and telecommunications utilities.
As a state legislator, Montgomery supported a complete repeal of the radioactive waste and cost safeguards on new nuclear power plants.
"Consumer advocates would naturally have concerns about somebody who seemed so supportive of industry now being in a position of overseeing those industries," Mike McCabe of Wisconsin Democracy Campaign, a WNPJ member group, told the Milwaukee Journal Sentinel.
Until recently, Montgomery also served on the Board of Directors for ALEC, a corporate-funded group notorious for pushing regressive state policies.
Montgomery's executive assistant at the PSC will be R.J. Pirlot, Wisconsin Manufacturers & Commerce's top lobbyist.
