As bugs and glitches continue to plague Healthcare.gov, the man who oversaw the site’s creation has said he’s resigning. Tony Trenkle, chief information officer at the Centers for Medicare and Medicaid Services (CMS), sent an e-mail to co-workers on Tuesday that said he will be leaving on November 15 “to take a position in the private sector.” Apparently, Trenkle’s resignation isn’t directly a result of the bungled Web site, but rather a management restructuring within the department, according to information sent to CNET by CMS. “Given the importance of the I.T. portfolio here, we’ve moved quickly to fill this position with another internal staff member who had vast experience and knowledge of the I.T. issue,” CMS Office of Communications director Julie Bataille said during a press call on Wednesday.
