Jason Levin, the Portland man who caused a ruckus over his plans to "infiltrate" Tea Party protests in an aim to discredit them, teaches in a Beaverton middle school and now faces an investigation by the Teacher Standards and Practices Commission. Melody Hanson, the commission's director of professional practices, said Wednesday that the agency opened an investigation because "there was enough concern that there was some neglect of duty" on the part of Levin.
