Between 1969 and 1973 he served in the JAG Corp of the US Army where he litigated criminal matters in special and general courts martial. He served as Chief of Military Justice in Danang, Vietnam 1971 to 1972. He also served as a staff lawyer on the Peers' Commission, which investigated the My Lai case.
Legal work
From 1973 to 2002 he worked as an attorney at Robertson, Monagle & Eastaugh Law Firm, a firm he eventually led. For his tireless efforts to keep the capitol in Juneau, the Juneau Chamber of Commerce named him person of the year in 1982. He represented the timber industry in Southeast Alaska, and has also been an advocate for public radio and the arts.
Chief of Staff
In 2001 he was named the head of Governor Frank Murkowski's transition team, and in 2002, he was appointed Chief-of-Staff by Governor Frank Murkowski. Although reluctant to leave the practice of law, which he loved, he said, "I am a strong believer in public service, and it is my turn to serve my State of Alaska, which has given so much back to me and my family." As Chief-of-Staff he directed the preparation of the State budget; oversaw the preparation of legislation; negotiated the budget and legislation with the Legislature; worked with the Governor and departmental commissioners to formulate policy. He also managed Governor's cabinet and served as the State's chief gas pipeline negotiator and successfully negotiated a draft contract between the Governor and the North Slope producers to construct a gas pipeline. During this time he was often referred to as "the most powerful unelected official in Alaska," although he always rejected this as he said his job was simply to carry out the will of Governor Murkowski, and noted that he was not acting on his own agenda.
Polar Pen charges dropped
In 2008, Clark admitted that he was aware that VECO Corporation had paid $10,000 for a political poll to gauge the popularity of then-incumbent Governor Murkowski, and was charged with honest services fraud. However, this statute was so vague it gave prosecutors "almost carte blanche power" to use in political and private situations which "should not be criminalized." Shortly thereafter, the US Supreme Court ruled that the honest services fraud statute was drafted with unconstitutional vagueness and could only cover "fraudulent schemes to deprive another of honest services through bribes or kickbacks supplied by a third party who ha not been deceived." Since Clark's awareness of the poll constituted neither bribes or kickbacks, all charges against him were voided. Moreover, due to misdeeds on behalf of the federal prosecutors in their "Polar Pen" operation, the prosecutors themselves were later investigated and found guilty of gross prosecutorial misconduct in the Ted Stevens case.
Current activities
Clark is currently working as an attorney in Juneau, Alaska. According to the Alaska Dispatch, he is also devoting his time to volunteering and grand-parenting.
