AUGUSTA –John McGough, the longtime chief of staff for Maine’s Republican Gov. Paul LePage, has resigned to take a new job with the U.S. Department of Health and Human Services. “John has been with me since I first ran for governor in 2010,” LePage said in a prepared statement Monday. “I have appreciated his leadership the past several years, and I congratulate him as he continues his career in public service at the federal level.” McGough has been LePage’s chief of staff since the governor first took office, and during the 2010 campaign he served as deputy chief of staff and policy director.
